Abstract
Disclosed are unsaturated isocyanurates of monourethanes of an aromatic polyisocyanate and a vinylidene carbonyl oxy alkanol characterized by one of the following formulae: ##STR1## wherein R.sub.1 is hydrogen or an alkyl group containing from one to four carbon atoms, R.sub.2 is hydrogen, alkyl containing from 1 to 12 carbon atoms, or a chlorinated, brominated, or fluorinated alkyl group containing from 1 to 12 carbon atoms, R.sub.3 is hydrogen, alkyl containing from 1 to 12 carbon atoms, or a chlorinated, brominated, or fluorinated alkyl group containing from 1 to 12 carbon atoms, R.sub.4 is hydrogen, methyl or ethyl, and n is from one to four, with the proviso that R.sub.2 and R.sub.3 on adjacent carbon atoms are not both alkyl or chlorinated, brominated, or fluorinated alkyl. The unsaturated isocyanurates may be homopolymerized or copolymerized with ethylenically unsaturated compounds to form isocyanurate polymers having excellent physical properties at high temperatures.
