ABSTRACT:
Isocyanurate polymers having improved physical properties are disclosed. Unsaturated isocyanates are prepared by reacting a polyisocyanate with a monohydric alcohol containing a vinylidene group to form an isocyanate-containing urethane and then reacting the isocyanate-containing urethane with tris(2-hydroxyethyl)isocyanurate to form an unsaturated isocyanurate. The unsaturated isocyanurate may be homopolymerized or copolymerized with ethylenically unsaturated compounds to form isocyanurate polymers having an excellent combination of physical properties.
