Abstract

The present invention provides polyols which can be obtained by a simple process. These polyols, unless explicitly specified, are to be understood to encompass both polyether polyols and polyether ester polyols. The invention further provides the simple process for the production of the polyols, and also, the production of polyurethanes comprising reacting a polyol according to the invention with a polyisocyanate.
