ABSTRACT OF THE DISCLOSURE Disclosed are unsaturated isocyanurates of monoure- thanes of an aromatic polyisocyanate and a vinylidene carbonyl oxy alkanol characterized by one of the following formulae: (1) (CH2 = ? - ? - O - CH2)3C - CH2OH (2) Image (3) Image (4) Image and (5) Image wherein R1 hydrogen or an alkyl group containing from one to four atoms, R2 is hydrogen, alkyl containing from 1 to 12 carbon atoms, or a chlorinated, brominated, or fluro- inated 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 con- taining from 1 to 12 carbon atoms, R4 is hydrogen, methyl or ethyl, and n is from one to four, with the priviso that R2 and R3 on adjacent carbon atoms are not both alkyl or chlor- inated, 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 tempe- ratures.
