Abstract
A polymerizable composition comprising an ethylinically unsaturated isocyanurate resin at least one vinyl monomer copolymerizable therewith. The isocyanurate resin is the trimerized reaction product of an ethylenically unsaturated, isocyanate functional urethane composition derived from the reaction of a polyisocyanate composition comprising a mixture of 2, 4'- and 4, 4'- diphenylmethane diisocyanates with at least one hydroxyl functionalized vinyl monomer. The polymerizable compositions are clear resins which can be reaction injection moulded to produce moulded articles having a high heat distortion temperature.
