Description

Aromatische Polyether mit olefinischen EndgruppenAromatic polyethers with olefinic end groups

Die Erfindung betrifft aromatische Polyether mit olefinischen polymerisierbaren Endgruppen. The invention relates to aromatic polyethers with olefinic polymerizable End groups.

Aromatische Polyether mit olefinischen Gruppen sind beispielsweise in der DE-OS 29 17 819 (US-PS 4 207 406) beschrieben. Hierbei handelt es sich z.B. um Copolymerisate von 2,6-Dimethylphenol und 2-Allyl-6-methyl--phenol. Versucht man derartige Copolymerisate mit anderen copolymerisierbaren Monomeren zu polymeriseren, so können leicht vernetzte unlösliche Produkte entstehen, deren weitere Verarbeitung schwierig ist. Aromatic polyethers with olefinic groups are for example in DE-OS 29 17 819 (US-PS 4 207 406). These are e.g. to copolymers of 2,6-dimethylphenol and 2-allyl-6-methylphenol. Tries to polymerize such copolymers with other copolymerizable monomers, so slightly crosslinked insoluble products can arise, their further processing is difficult.

Außerdem sind acylgekoppelte Polymere von chinongekoppelten Polyphenylenoxiden bekannt, die unter anderem als Acylkomponente die Maleinsäure enthalten können (DE-OS 28 22 859 US-PS 4 156 77). Diese mit Maleinsäure gekoppelten Polyphenylenoxide sind aber z.B. nicht geeignet, mit anderen Doppelbindungen enthaltenden Monomeren zu copolymerisieren, so daß sie als Copolymerisationskomponenten nicht in Frage kommen. In addition, acyl-coupled polymers are quinone-coupled polyphenylene oxides known, which may contain maleic acid as an acyl component (DE-OS 28 22 859 U.S. Patent 4,156,77). These are maleic acid coupled polyphenylene oxides but e.g. not suitable to work with other monomers containing double bonds copolymerize, so that they are out of the question as copolymerization components.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, aromatische Polyether mit olefinischen, polymerisierbaren Endgruppen zu schaffen. The present invention is based on the object of aromatic To create polyethers with olefinic, polymerizable end groups.

Die Aufgabe wird erfindungsgemäß gelöst, durch aromatische Polyether, die eine olefinische Endgruppe der allgemeinen Formel enthalten wobei Wasserstoff oder ein aliphatischer Alkylrest sein kann.The object is achieved according to the invention by aromatic polyethers which contain an olefinic end group of the general formula where hydrogen or an aliphatic alkyl radical can be.

'Gegenstand der Erfindung sind daher Polyphenylenether des Patentanspruches 1.The invention therefore relates to the polyphenylene ethers of the patent claim 1.

Ein weiterer Gegenstand der Erfindung ist die Verwendung der olefinische Endgruppen enthaltenden Polyphenylenether nach Anspruch 1 zur Herstellung von Copolymerisaten mit anderen polymerisierbare Doppelbindungen enthaltenden Verbindungen. Another object of the invention is the use of the olefinic Polyphenylene ether containing end groups according to Claim 1 for the production of copolymers with other compounds containing polymerizable double bonds.

Unter aromatischen Polyethern werden Polyphenylenoxide verstanden, bei denen der Ethersauerstoff der einen Einheit an den aromatischen Ring der benachbarten Einheit gebunden ist. Bevorzugt handelt es sich bei den Polyethern um Verbindungen auf der Basis von in ortho-Position disubstituierten Polyphenylenoxiden. Dabei sollen mindestens 20 Einheiten miteinander verknüpft sein. Die Polyether können in ortho-Stellung zum Sauerstoff Wasserstoff, Halogen, Kohlenwasserstoffe, Halogenkohlenwasserstoffe, Phenylreste und Kohlenwasserstoff-oxi-Reste tragen. So kommen in Frage: Poly(2,6-dichlor-1,4-phenylen)-ether, Poly(2,6-diphenyl-1,4-phenylen)ether, Poly(2,6-dimethyl-1,4-phenylen)-ether, Poly(2,6-dibrom--1,4-phenylen)ether Derartige Polyether haben freie phenolische Hydroxylendgruppen. Aromatic polyethers are understood to mean polyphenylene oxides, in which the ether oxygen of one unit is attached to the aromatic ring of the neighboring Unity is bound. The polyethers are preferably compounds based on polyphenylene oxides disubstituted in the ortho position. This should at least 20 units must be linked together. The polyethers can be in the ortho position to oxygen hydrogen, halogen, hydrocarbons, halogenated hydrocarbons, Wear phenyl radicals and hydrocarbon-oxy radicals. So come into question: Poly (2,6-dichloro-1,4-phenylene) -ether, Poly (2,6-diphenyl-1,4-phenylene) ether, poly (2,6-dimethyl-1,4-phenylene) ether, poly (2,6-dibromo-1,4-phenylene) ether Such polyethers have free phenolic hydroxyl end groups.

Die aromatischen Polyether werden u.a. durch Selbstkondensation der entsprechend einwertigen Phenole durch Einwirken von Sauerstoff in Gegenwart eines Katalysatorsarstems, wie es beispielsweise in den US-PSen 3 219 625, 3 306 874, 3 306 875, 3 956 442, 3 965 o69, 3 972 851 beschrieben ist, hergestellt. The aromatic polyethers are produced, among other things, by self-condensation of the correspondingly monohydric phenols by the action of oxygen in the presence of a Catalyst systems, as described, for example, in US Pat. Nos. 3,219,625, 3,306,874, 3,306,875, 3,956,442, 3,965,069, 3,972,851.

Bei den olefinischen polymerisierbaren Endgruppen handelt es sich um eine vinylische bzw. allylische Gruppierung. Bevorzugt sind vinylische Endgruppen.The olefinic polymerizable end groups are a vinylic or allylic group. Vinylic end groups are preferred.

Die Herstellung der aromatischen Polyether mit olefinischer Endgruppe erfolgt u.a. durch die Umsetzung der freien phenolischen Hydroxylendgruppe mit einer Verbindung, die eine vinylische Endgruppe und eine mit der Hydroxylendgruppe des aromatischen Polyethers reagierende, zu einer Verknüpfung von Polyether und vinylischer Endgruppe tragenden Verbindung enthält. Beispielsweise kommen in Betracht eine olefinische Doppelbindung enthaltende Säurehalogenide, -anhydride bzw. -ester, Epoxide und Isocyanate. In Frage kommen beispielsweise: Acrylsäurechlorid, Methacrylsäurechlorid, Methacrylsäureanhydrid, p-Vinyl-benzoylchlorid, Vinylphosphonsäuredichlorid> Vinylsulfonsäurechlorid, Vinylisocyanat, Vinylchloriden. The production of aromatic polyethers with olefinic end groups takes place, among other things, by the reaction of the free phenolic hydroxyl end group with a Compound having one vinylic end group and one with the hydroxyl end group of the aromatic polyether reacting to a linkage of polyether and vinylic Contains end group bearing compound. For example, an olefinic one can be considered Acid halides, anhydrides or esters containing double bonds, epoxides and isocyanates. For example: acrylic acid chloride, methacrylic acid chloride, methacrylic anhydride, p-vinyl benzoyl chloride, vinyl phosphonic acid dichloride> vinyl sulfonic acid chloride, Vinyl isocyanate, vinyl chlorides.

Bevorzugt ist dabei Methylacrylsäurechiorid Vinylphosphonsäuredichlorid und Vinylphosphonsäurechlorid. Methylacrylic acid chloride vinyl phosphonic acid dichloride is preferred and vinyl phosphonic acid chloride.

Bevorzugt sind Polyphenylenether,-die eine olefinische Endgruppe der allgemeinen Formel enthalten worin R die oben angegebene Bedeutung hat und A folgende Gruppierung sein kann.Polyphenylene ethers which contain an olefinic end group of the general formula are preferred in which R has the meaning given above and A has the following grouping can be.

Die Umsetzung des aromatischen Polyethers mit diesen Verbindungen erfolgt bevorzugt in organischen Lösungsmitteln wie es beispielsweise in der Schrift "The chemistry of the hydroxyl group Part 1 S. 453 bis 503 (1971) Interscience Publishers Landon - New York -Sydney - Toronto - von S. Patai beschrieben ist. Die Reaktion kann dabei in Gegenwart von Katalysatoren wie tert. Amine oder sogenannten "Phasentransferkatalysatoren" wie quartären Ammonium-, Phosphonium-, Arsenium- und tertiären Sulfonium-Verbindungen erfolgen.The reaction of the aromatic polyether with these compounds preferably takes place in organic solvents such as, for example, in the scriptures "The chemistry of the hydroxyl group Part 1 pp. 453-503 (1971) Interscience Publishers Landon - New York - Sydney - Toronto - is described by S. Patai. The reaction can in the presence of catalysts such as tert. Amines or so-called "phase transfer catalysts" such as quaternary ammonium, phosphonium, arsenium and tertiary sulfonium compounds take place.

Die erfindungsgemäßen aromatischen Polyether können z.B. als Komponente für Mischungen mit anderen Polymeren wie Polystyrol, ABS verwendet werden. Insbesondere können die Polyether mit anderen doppelbindungshaltigen polymerisierbaren Verbindungen, wie beispielsweise Styrol, Acrylnitril, Methacrylsäuremethylester, Alkylester der Acrylsäure, Butadien, Isopren copolymerisiert werden. Es können aber auch Terpolymerisate hergestellt werden, die aus den aromatischen Polyethern mit olefinischer Doppelbindung und zwei weiteren doppelbindungshaltigen Verbindungen, wie beispielsweise Styrol/ Acrylnitril, Styrol/Maleinsäuranhydrid, Styrol/Butadien, Acrylnitril/Butadien aufgebaut sind. Solche Copolymerisate eignen sich z.B. als thermoplastische Kunststoffe oder in Kombination mit phosphonhaltigen Verbindungen zur Flammfestausrüstung von thermoplastischen Kunstst ffen.For example, the aromatic polyethers of the present invention can be used as a component can be used for blends with other polymers such as polystyrene, ABS. In particular the polyethers can be combined with other polymerizable compounds containing double bonds, such as styrene, acrylonitrile, methyl methacrylate, alkyl esters Acrylic acid, butadiene, isoprene can be copolymerized. However, terpolymers can also be used are made from the aromatic polyethers with an olefinic double bond and two other compounds containing double bonds, such as styrene / Acrylonitrile, styrene / maleic anhydride, styrene / butadiene, acrylonitrile / butadiene are. Such copolymers are suitable, for example, as thermoplastics or in combination with phosphone-containing compounds for the flame-retardant finishing of thermoplastics Plastic.
