Abstract

The present disclosure relates to processes for the production of a polyurethane material, where (a) di- and/or polyisocyanates, (b) compounds which have hydrogen atoms reactive toward isocyanate groups and which do not include compounds having carbon-carbon double bonds, (c) compounds including at least one carbon-carbon double bond, (d) optionally catalyst that accelerates the urethane reaction, and (e) optionally other auxiliaries and additives are mixed to give a reaction mixture and the mixture is hardened at temperatures above 120° C. The present disclosure further relates to a polyurethane material obtainable by this process, and also to the use of the polyurethane material, in particular of a polyurethane fiber-composite material as structural components.
