BASE-CATALYZED ALKOXYLATION IN THE PRESENCE OF NON-LINEAR POLYOXYETHYLENE-CONTAINING COMPOUNDS

摘要

The present invention provides a long-chain polyether polyol having a number average molecular weight of greater than about 1,200 g/mole and produced by alkoxylating an initiator with an aikylene oxide in the presence of a basic catalyst having at least one cation thereof chelated with a non-linear polyoxyethylene-containing compound having a functionality of at least about three. The long-chain polyether polyols of the present invention may find use in providing flexible polyurethane foams and non-cellular polyurethanes.
