ABSTRACT:
Thermoset products are prepared by polymerizing (A) at least one thermosettable compound which contains both a maleimide group and a cyanate group such as 3-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)phenyl cyanate and optionally (B) at least one of (1) at least one aromatic polycyanate such as bisphenol A dicyanate; (2) at least one polymaleimide such as N,N'-(methylenedi-p-phenylene)bismaleimide; (3) at least one material having an average of more than one vicinal epoxide group per molecule such as a diglycidyl ether of bisphenol A; (4) at least one polymerizable ethylenically unsaturated material such as styrene; or (5) a mixture of any two or more of components 1-4 in any combination.
