LONG CHAIN POLYETHER POLYOLS

摘要

The present invention provides a long-chain polyether polyol having a number average molecular weight of greater than about 500 g/mole and produced by alkoxylating a polyoxyethylene-containing initiator with an alkylene oxide in the presence of a basic catalyst having at least one cation thereof chelated by the polyoxyethylene-containing initiator. The inventive long-chain polyether polyols may be used to provide flexible polyurethane foams and non-cellular polyurethanes.
