Abstract: A low viscosity, stable graft polymer dispersion is prepared by polymerizing in the presence of a free radical initiator, from about 25 to about 75 weight percent based on the total weight of the dispersion, an ethylenically unsaturated monomer or mixture of monomers, in a polyol mixture comprising (1) from about 25 to about 99 weight percent of a polyol containing from 2 to 8 hydroxyl groups and having an equivalent weight from 30 to about 200, (2) from about 1 to about 75 weight percent of a macromer containing induced unsaturation, said macromer comprising the reaction product of a polyether polyol having an equivalent weight from 100 to 10,000 with a compound having both ethylenic unsaturation and a group selected from the group consisting of a hydroxyl, carboxyl, anhydride, isocyanate and epoxy or mixtures thereof. These graft polymer dispersions are useful for preparing polyurethane products.
