Abstract

A graft copolymer dispersion is produced by polymerizing a mixture comprising by weight approximately PA0 (a) 1 to 99% of an organopolysiloxane mass containing Si-H groups and vinyl groups, and PA0 (b) 99 to 1% of a polymerizable vinyl monomer. Polymerization initiators and/or molecular weight controllers may also be present. The product is not crosslinked as produced but can be blended with a crosslinking agent, applied to a textile as a coating and the crosslinked.
