Abstract
The present invention relates to graft polyols employing a t-amyl peroxy compound as free radical initiator. The novel graft polyols are made by polymerizing at least one monomer in a polyol composition in the presence of a free radical initiator and preferably a chain transfer agent. The resulting graft polyols are in turn useful in reactions with polyisocyanates to make polyurethane products.
