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,Nʹ-(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.
热固性产品是通过聚合至少一种含有马来酰亚胺基团和氰酸基团的热固性化合物(如3-(2,5-二氢-2,5-二氧杂-1H-吡咯-1-基)苯基氰酸酯)(A)制备的,可选地还包括至少一种以下材料之一(B):(1)至少一种芳香族聚氰酸酯(如双酚A二氰酸酯);(2)至少一种聚马来酰亚胺(如N,N'-(亚甲基二-p-苯二亚甲基)双马来酰亚胺);(3)至少一种每个分子平均含有多于一个邻二氧环氧基团的材料(如双酚A的二环氧基醚);(4)至少一种可聚合的乙烯基不饱和材料(如苯乙烯);或(5)组分1-4中任意两种或两种以上的混合物以任何组合形式。
