Abstract

Process for obtaining polyisocyanates with blocked isocyanate groups containing uretdione groups, characterized in that an organic polyisocyanate is transformed into an intermediate product containing uretdione groups and free isocyanate groups, and this intermediate product, if appropriate before and/or during and/or after reaction with defective amounts of a chain extension agent of molecular weight 18-300, bearing 2-3 groups capable of reacting with respect to isocyanate groups, by reaction with a monofunctional blocking agent in the direction of the reaction from polycyanate of isocyanate, it is transformed into the corresponding compound containing uretdione groups and blocked isocyanate groups, as well as, if necessary, in the chain urethane and/or urea groups.
