POLYURETHANE BASED ON RENEWABLE RAW MATERIALS

摘要

The invention relates to polyurethanes based on at least one polyisocyanate and at least one polyester polyol, wherein the polyester polyol is based on at least one polyhydric alcohol and a mixture consisting of at least two dicarboxylic acids, wherein at least one of the at least two dicarboxylic acids are obtained at least partially from newneable raw materials. The invention also relates to a method for producing said type of polyurethane and moulded bodies containing said type of polyurethane. Said claimed polyurethanes display a low tendency for blooming.
