- PROCESS FOR MAKING GRAFT POLYOLS USING T-AMYL PEROXY FREE RADICAL INITIATOR

摘要

The present invention relates to graft polyols using t-amyl peroxy compounds as free radical initiators. The new graft polyols are prepared by polymerizing one or more monomers in the polyol composition in the presence of a free radical initiator and preferably a chain transfer agent. The graft polyols formed are also useful for the reaction with polyisocyanates to produce polyurethane products.
