Abstract:
The present 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 of two or more dicarboxylic acids, wherein at least one of the two or more dicarboxylic acids is at least partly obtained from renewable raw materials, to processes for producing such polyurethanes and also to moldings comprising such polyurethanes. The polyurethanes of the present invention have minimal tendency to bloom.
