ABSTRACT:
This invention is directed to a shelf-stable, powder composition adapted to form a high T.sub.g, thermally stable, impact resistant thermoset material. The composition consists essentially of a mixture of an allyl-functional prepolymer component and polymaleimide component. The allyl-functional prepolymer component is the reaction product of an aromatic allyl-functional compound and a modifying compound wherein the compounds contain mutually reactive funtionalities such as an aromatic allyl-functional epoxide compound and a modifying amine compound.
