    Abstract: Process for the preparation of a macromer suitable as a stabiliser precursor in a polymer polyol, which process comprises reacting a polyol with a cyclic dicarboxylic acid anhydride not containing any polymerizable double bond, and subsequently reacting the adduct thus obtained with an epoxide compound containing a polymerisable double bond. The resulting macromer has a nominal molecular weight of at least 4000 and can be applied for the preparation of a polymer polyol by polymerizing in a base polyol at least one ethylenically unsaturated monomer in the presence of a polymerization initiator and a macromer. The polymer polyol thus obtained is very suitable for manufacturing flexible polyurethane foams.
