摘要
A method of forming a polyol includes the steps of reacting an initiator with an alkylene oxide, and optionally carbon dioxide, in the presence of a double metal cyanide catalyst and a sterically hindered chain transfer agent capable of protonating the growing polyol polymer. The presence of the chain transfer agent reduces the polydispersity of the resultant polyol.
