| abstract |
The invention relates to at least one polyisocyanate a based on hexamethylene diisocyanate a containing from 10 to 50% by weight of at least one oligomeric polyisocyanate based on hexamethylene diisocyanate and optionally monomeric hexamethylene diisocyanate a. -1) and at least one polyisocyanate based on isophorone diisocyanate containing from 50 to 90% by weight of at least one oligomeric polyisocyanate based on isophorone diisocyanate and optionally monomeric isophorone diisocyanate a-2) and at least one component containing sulfur, provided that at least one of components a-1) and a-2) further comprises monomeric isocyanates of the mentioned types, respectively; It is about. Mixtures of certain components mentioned above containing isocyanate groups have been shown to improve the thermal and mechanical properties of the cured composition. Molded articles produced in this way are particularly suitable for producing spectacle lenses due to the above properties. |
