    摘要： A graft copolymer dispersion is produced by polymerizing a mixture comprising by weight approximately(a) 1 to 99% of an organopolysiloxane mass containing Si-H groups and vinyl groups, and(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.
