ABSTRACT:
A process is disclosed for preparation of novel epoxy-substituted aralkyl isocyanates by reaction of tertiary aralkyl olefins and an epoxidizing agent at a temperature of from -35.degree. C. to about 50.degree. C. The compounds are useful as intermediates to produce curing agents for polyfunctional active hydrogen-containing compounds, e.g., by reaction with polyols to produce epoxy-pendant urethanes and then with polyamines, and the like.
