Abstract
Process for preparing modified polymer polyols, characterized in that it comprises polymerizing a monomer mixture in the presence of a polyether polyol having a molecular weight of the order of 1,000 to 10,000 and a free radical polymerization catalyst, the monomer mixture consisting of 10-80 % methyl methacrylate, 90-20% acrylonitrile and 0-10% of a monomer having at least two polymerizable olefinic groups, on a weight basis, and used in an amount of 2 to 80% by weight based on the combined weight of the polyester polyol and monomers.
