Abstract

Disclosed is a process for the preparation of ethylenically unsaturated isocyanurates which comprises a first step of trimerizing an aromatic polyisocyanate in the presence of an isocyanate trimerization catalyst and an ethylenically unsaturated solvent wherein at least 20% by weight of the solvent is an ethylenically unsaturated polar solvent, to form an isocyanate-containing isocyanurate and a second step of reacting the isocyanate-containing isocyanurate with a monohydric alcohol containing a vinylidene group to form an ethylenically unsaturated isocyanurate. The resulting solution of an ethylenically unsaturated isocyanurate dissolved in an ethylenically unsaturated solvent may be cured to form resins having excellent high temperature resistant properties.
