Abstract:
A high secondary hydroxyl group-content polyoxypropylene polyol prepared by the double metal cyanide catalyzed oxypropylation of a suitably hydric initiator having a cap comprising polymerized propylene oxide moieties, said polyol comprising in most major part a polyoxypropylene polyol having an average equivalent weight of from about 1000 Da to about 15,000 Da and a random, internal oxyethylene content of from about 0.5 weight percent to about 15 weight percent and a polyoxyalkylene tail having an average molecular weight greater than about 80,000 Da, said tail containing oxypropylene and oxyethylene moieties, said polyoxypropylene polyol having a homopolyoxypropylene cap which constitutes less than about 15 percent by weight of said polyol.
