Definitions
- the invention relates to a polymer dispersion comprising water and at least 60% by weight of an organic polymer which comprises at least one group of the general formula I.
- A is CH 2 or a linear or branched, saturated or unsaturated alkylene radical having 2 to about 12 C atoms or an arylene radical having about 6 to about 18 C atoms or an arylene alkylene radical having about 7 to about 19 C atoms
- Z represents CH 3 , O-CH 3 or a linear or branched, saturated or unsaturated alkyl radical or alkoxy radical having 2 to about 12 carbon atoms and n represents 0, 1 or 2, or a condensation product of at least two such groups.
- the invention also relates to a composition which has an organic polymer which has at least one group of the general formula I and contains at least one further organic polymer or a mixture of two or more further organic polymers.
- Silane-terminated, moisture-curing one-component polyurethane compositions are increasingly being used as flexible coating, sealing and adhesive compositions in construction and in the automotive industry.
- Such Applications place high demands on the stretchability and adhesive power as well as on the curing speed.
- silane-terminated polymers often have water-repellent properties, which give the sealing, coating or adhesive compositions prepared therefrom excellent water resistance and heat resistance.
- Alkoxysilane-terminated polymers are known from the prior art and are used as soft-elastic sealing, coating and adhesive compositions.
- EP-B 0 549 626 describes alkoxysilane-terminated, moisture-curing one-component polyurethanes which are used, for example, as joint sealing compounds.
- the disclosed compounds have a quick skin formation and quick stickiness, even after prolonged storage.
- a disadvantage of the compounds described, however, is that, because of their reactive end groups, they have to be stored with the exclusion of moisture and there is a risk of irreversible changes in properties over a longer storage period.
- DE-A 36 37 836 describes an aqueous silicone dispersion which can be obtained from an OH-terminated polydiorganosiloxane, (organo) metal compounds and a siliconate.
- the products described have a curing time of at least one day.

- DE-C 42 15 648 relates to a dispersion of alkoxysilane-terminated polymers which have amino groups capable of salt formation in the polymer chain. Dispersions with a maximum solids content of 41 are described % By weight. If such dispersions are used for the bonding of absorbent materials, the high water content leads to a high loading of the substrate with water. In the case of paper gluing, for example, this can lead to shape changes in the substrate which are not desired.

- the polyurethanes described have hydrolyzable or hydrolyzed silyl end groups and have solubilizing or emulsifying groups, in particular carboxyl groups, in the polymer backbone.
- the dispersions described have polymer contents of up to about 40% by weight.
- the polymers described must also have urea groups which are produced in water by chain extension of a prepolymer with isocyanate end groups.
- the compounds described show a strong formation of coagulum and have only unsatisfactory water resistance.
- the problem with all dispersions of silanol-terminated polyurethanes known from the prior art is that only low solids contents can be achieved.
