POLYETHER POLYOLS, METHOD FOR PRODUCING POLYETHER POLYOLS, AND USE THEREOF FOR PRODUCING POLYURETHANES.

摘要

The invention relates to a method for producing polyether polyols, wherein at least one hydroxyl group-containing fatty acid ester and/or at least one hydroxyl-modified fatty acid ester is caused to react in each of at least two method steps with a mixture of ethylene oxide and at least one further alkylene oxide different from ethylene oxide, using a double metal cyanide catalyst.
