Abstract: The present invention relates to a process for the preparation of stable graft polymer dispersions having improved dispersibility by a free radical polymerization of an ethylenically unsaturated monomer under conditions of no-reflux or alternatively under conditions that do not return the evaporated monomer to the dispersion. Polyurethane foams may be prepared from these polymer dispersions.

Abstract: Vinyl resin compositions are disclosed which possess improved lubricity, mold releasability, water repellency, abrasion resistance, gloss and/or processability. These improvements are obtained by mixing with the vinyl resin a minor portion of an organopolysiloxane which bears one or more acyloxyhydrocarbyl radicals bonded to silicon in the organopolysiloxane.
