摘要：
Thermosetting compositions comprise (a) about 10 % to about 60 % of a polymerizable olefinic monomer such as styrene or vinyl toluene (b) from about 1 to about 40 % of a maleimide of formula (I), where R1 and R2 are independently selected from hydrogen or C1-3 alkyl groups, and in which the phenyl group may be substitued with aliphatic, alicyclic, and aromatic groups and up to three halogen or hydroxyl groups, and (c) about 5 % to about 89 % unsaturated polyester. The compositions are useful for their electrical and heat resistant properties as molding compositions, for the impregnation of electrical coils and for encasing electrical components.
