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

摘要

The present invention relates to graft polyols employing a t-amyl peroxycompound as free radical initiator. The novel graft polyolsare made by polymerizing at least one monomer in a polyol composition in thepresence of a free radical initiator and preferably a chaintransfer agent. The resulting graft polyols are in turn useful in reactionswith polyisocyanates to make polyurethane products.
