Mo-2999 LeA 24,941 PROCESS FOR THE PRODUCTION OF MOLDED POLYURETHANE PARTS ABSTRACT OF THE INVENTION The present invention is directed to a process for the production of light-resistant, optionally foamed elastomeric molded polyurethanes by reacting, a) organic polyisocyanates which are either mixtures of isophorone diisocyanate with polyisocyanates containing isocyanurate groups ant based on 1,6-diisocyanatohexane or mixtures of IPDI with polyisocyanates containing isocyanurate groups and based on 1,6-diisocyanato-hexane and IPDI with organic compounds containing isocyanate- reactive groups in the presence of catalysts, wherein the components are reacted together inside closed molds in an isocyanate index of about 70 to 130. The present invention is additionally directed to the elastomeric polyurethanes prepared by this process.
