Abstract
ABSTRACT
A pigmented thermoplastic polymer masterbatch composition comprises a polyester of melting point above 200°C based on polyethylene terephthalate, a second polymer to plasticize the polyester/and pigment in an amount of at least 20 parts per 100 parts of composition. The second polymer can be also a toughening agent for the PET and can be a polycaprolactone, or a copolymer of ethylene with acrylic acid or vinyl acetate.

Description
Improvements in or relating to thermoplastic polymer compositions This invention relates to thermoplastic polymer compositlons and more par~icularly to compositions which can be used as masterbatches ~or pigmentation purposes, and to methods o~ using such compositions.
Thermoplastic polymers such as those based on polyethylene terephthalate (PET) are now in use in mou.ding compositions in the plastics industry, but being engineering thermoplastics they are frequently in use in relatively small components and tonnages. It is therefore convenient to colour PET
compositions by masterbatching techniques owing to the low tonnages involved and the fact that "dry" colouring with pigments, is messy and can lead to uneven results.
1; :6~LS~
Commeraial masterbatches are available which can be used to colour PET
compositions but t~ese have drawbacks in that i) They are based on low melting point polymers which melt at the drying temperatures for PET making it impossible to dry or redry polymer once blended.
ii) The presence of low melting point polymer adversely affects certain properties, particula,rly heat distortion temperature and flammability.
A possible solution to the problem was to make masterbatches based on PET
itself. This would eliminate any drying problems, in that polymer composition and masterbatch would require the same conditions. Thus trials were carried out,but it was found that attempts ~to make master-batches by incorporating high pigment loadings eg 30 to 40~ by weight into PET failed because too high a torque was generated~in the compounding extruder. Masterbatches~ containing less than 20~ by weight of pigment would not be acceptable because in use too much would have to be used thus adversely aPfecting the properties of the final pigmented composition.
Masterbatches based on low moleoular weight co-palyesters are desoribed in UK~Pàtert No. 1,490,320 but thése are Por colouring fibre or film grade polyesters and deliberately avoid the ~use of PET itself as the base polymer.
: ~ ~
European Patent ~o. 0 114 386 also describes colourant masterbatches for PET. In this~patent a particular recrystaLlisation exotherm is specified and the colourant carrier used is a mixture of a linear polyester of softening point over 60C and polybutylene terephthalate. The Iinear polyesters used have softening points uell below that of PET itself.
We have now found that it is ~pos~ible to manufacture extremely useful masterbatches if a small~proportion of other polymer is incorporated into PET/pigment mixture for masterbatching.

- 3 - ~ ~ 6 ~ ~ ~t7 Thus according to the present invention a pigmented thermoplastic polymer masterbatch composition comprises a polyester having a melting point above 200C and based on polyethylene terephthalate repeating uniks, a second solid polymer capable o~ plasticizing said polyester, and at least 20 parts by weight of piement per hundred parts by weight of composition, the amount of said second polymer being sufficient to ~acilitate wetting out of the pigment in the polymer composition.
The second polymer will generaIly soften at a much lower temperature than PET,for example in the range 50C to 120C. Preferably also the second polymer is one ~hich will toughen the resulting composition. Suitable toughening polymers include polycaprolactones, copolymers of ethylene with unsaturated carboxylic acid monomers such as ethylene-acrylic acid copolymers, and copolymers of ethylene with unsaturated esters such as ethylene-vinyl acetate copolymers.
.
Preferably the toughening, plastlcizing polymer has a melting point in the range 50C to 100C. One preferred second polymer is ethylene-acrylic acid copolymer. Other preferred second polymers are polycaprolactones, which ~ay have moleoular weights of from 200 to 100,000 although particularly preferred are poIycaprolactones of molecular weights greatèr than 20,500 sinoe these have other beneficial e~fects in PET compositions as discussed in UK Patent Application No. 2,125,057A. ~
The amount of the second polymer will g nerally be in the range 2 to 20 parts by weight per 100 parts by weight of total polymer.
.
Pigment may be incorporated in the masterbatch composition in high 25~ loadings eg 60 percent by weight of total composition. ~ It is preferred that the masterbatch contains as hi&h a loading as practicable, to minimise dilution of the composition being pigmented, the preferred loadings being in the range 30 to 60~percent.
Tne masterbatch composition is used to pigment PET compositions simply by adding a minor proportion of masterbatch to the composition being pigmented and blending~the two together, for example in a tumble blender.
PET compositions o~ the type described and claimed in UK Patent Application No. 2j125,057A may be pigmented in this way but the masterbatch composition may equally well be used in other PET compositions.
~' The invention will now be more particularly described by means of examples.
Examplas 1 and 2 In Example 1 a commercial masterbatch containing S0~ cadmium red pigment in EVA was dry blended at an addition level of 3% in a commercially available PET moulding composition (BEETLE PET 804F ex BIP Chemicals Limited). This was in~ection moulded to give a particular red colour. In Example 2, a PET
masterbatch comprising 63 parts of a PET of melting point 255C, 7 parts *CAPA 601P (polycaprolactone of number average molecular weight 45,000-50,000 and meiting point 60 commercially available from Interox Chemicals Ltd) and 30 parts cadmium red pigment was easily compounded on a Welding Engineers extruder. A similar masterbatch without polycaprolactone would not process successfully on a Welding Engineers extruder. This was dry blended at an addition level of 5% in Beetle PET 804F and injection moulded to give the same red colour. Properties of the two sets of mouldings are compared below:
