ABSTRACT:
Vinyl polymer polyols made by polymerizing in situ via a free-radical mechanism one or more vinyl monomers in an epoxy resin-modified polyol are described. Preferably, styrene and acrylonitrile are copolymerized in a polyol made by adding epoxy resin to the alkoxylation of a polyol initiator having 3 to 4 hydroxyl groups. The vinyl polymer polyols of this invention give flexible polyurethane foams with greater load-bearing properties.
