Abstract

A coating or molding composition including a polyisocyanate and an unsaturated imide, and having a ratio of total isocyanate functions to total polymerizable double bonds in the imide in the range of from 0.3 to 15, in addition polymerized to hard, imide group containing polymers characterized by the recurring unit: ##STR1## Coatings and shaped articles formed from such polymers are hard, tough, thermally stable, solvent resistant and are good insulators.
