POLYETHER POLYOLS, PROCESS FOR PREPARING POLYETHER POLYOLS AND THEIR USE FOR PRODUCING POLYURETHANES
摘要:
The present invention relates to a process for preparing polyether polyols, in which at least one hydroxyl-comprising fatty acid ester and/or at least one hydroxyl-modified fatty acid ester is reacted with the aid of a double metal cyanide catalyst in at least two process sections with in each case a mixture of ethylene oxide and at least one further alkylene oxide different from ethylene oxide.
