ABSTRACT:
Cured resins having excellent thermal and abrasion resistance and improved processability are provided by the addition polymerization of a compound having isocyanurate moieties, imide and/or amic acid moieties and ethylenically unsaturated moieties. An example of such a compound is the reaction product of an unsaturated cyclic anhydride such as maleic anhydride, an organic polyisocyanate such as a polymeric methylene phenyl polyisocyanate and water.
