Abstract

Preparation process for polyurethanes based on hydrolytically stable polyesters, characterized in that a polyester is reacted with a stoichiometric excess of an organic diisocyanate and additionally by reacting the product formed with an organic epoxide having a molecular weight greater than 60.
