Esters of carboxy amino phenyl isocyanurates and vinylidene carbonyl oxy alkanols of the following formulae
are prepared, and wherein R1 is hydrogen or an alkyl group containing from one to four carbon atoms, R2 is hydrogen, alkyl containing from 1 to 12 carbon atoms, or a chlorinated, brominated, orfluorinated alkyl group containing from 1 to 12 carbon atoms, R3 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, R4 is hydrogen, methyl or ethyl, and n is from one to four, with the proviso that R2 and R3 on adjacent carbon atoms are not both alkyl or chlorinated, brominated, or fluorinated alkyl. These unsaturated isocyanurates may be homopolymerized or copolymerized with ethylenically unsaturated compounds to form isocyanurate polymers having excellent physical properties at high temperatures.
