| abstract |
The present invention relates to a composition comprising 10 to 50 wt.-% of at least one polyisocyanate a-1) based on hexamethylene diisocyanat, comprising at least one oligomeric polyisocyanate based on hexamethylene diisocyanate and optionally monomeric hexamethylene diisocyanate and 50 to 90 wt.-% of at least one polyisocyanate a-2) based on isophorone diisocyanate, comprising at least one oligomeric polyisocyanate based on isophorone diisocyanate and optionally monomeric isophorone diisocyanate, with the proviso that at least one of the components a-1) and a-2) additionally comprises monomeric isocyanate of the named kind, as well as at least one sulfur-containing component. It has been shown that the above mentioned mixture of the specific isocyanate group containing components improves the thermal and mechanical properties of a cured composition. Thus prepared molded articles are particularly suitable for the preparation of spectacle lenses, inter alia due to these properties. |
