ABSTRACT:
An organopolysiloxane/acrylate ester copolymer emulsion composition is prepared by forming a water-based emulsion of an alkenyl-containing organopolysiloxane containing no more than 5,000 parts per million of organosiloxane oligomer which has .ltoreq.20 silicon atoms in its molecule and copolymerizing the emulsion with an acrylate ester monomer. The resultant copolymer does not suffer from disadvantages of prior art systems, such as staining in applications as a paint or water repellent, staining in fiber treatment applications, or reduction of adhesion when the copolymer is used as a release coating.
