Abstract
The present invention relates to a polymer dispersion wherein the components of a physical mixture comprising (i) at least one unsaturated silane of the general formula (I): [HC═CX(Y)]Si(CH)(R)in which X is a hydrogen atom or a methyl group, Y is a divalent group selected from —CH— and —C(O)O—(CH)—, n is 0 or 1, R is an alkoxy group selected from methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, isobutoxy, and 2-methoxyethoxy, and p is 0 or 1, and (ii) at least one organosilane of the general formula (II): RSi(CH)(R)in which Ris a linear, branched or cyclic alkyl group having 1 to 18 carbon atoms or is an aryl group or is a polyether group, Ris an alkoxy group selected from methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, isobutoxy and 2-methoxyethoxy, and q is 0 or 1, and/or at least one silicic ester of the general formula (III): Si(R), in which groups Rare identical or different and Ris an alkoxy group selected from methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy and isobutoxy, are incorporated into the framework of the polymer, a process for preparing such a polymer dispersion, and its use.
