ABSTRACT:
Polymerizable compositions are disclosed which comprises a mixture of (A) at least one thermosettable compound which simultaneously contains both a maleimide group or substituted maleimide group and a cyanate group such as 3-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)phenyl cyanate and (B) at least one material containing a plurality of aromatic amine groups such as 4,4'-diaminodiphenylmethane. Also disclosed are mixtures of the above polymerizable compositions and (C) at least one other material selected from (1) aromatic polycyanates, (2) polymaleimides, (3) materials having an average of more than one vicinal epoxide group per molecule, (4) a polymerizable ethylenically unsaturated material and (5) any combination thereof. The cured, polymerized products are useful as coatings, structural or electrical laminates or composites, castings, and the like.
