ABSTRACT:
Graft copolymer dispersions of low viscosity and improved particle size distribution are prepared by mixing a free radical catalyst and a vinyl monomer in a static mixer and thereafter adding the catalyst-monomer mix to a polyol. The dispersions are low viscous liquids which may be advantageously employed in the preparation of polyurethanes.
