    摘要： A polyamino triazine, such as melamine or benzoguanamine, etc., is reacted with an aldehyde such as formaldehyde, and a vinyl compound containing two active hydrogens capable of reaction with an aldehyde or alkylol group in such a manner as not to react with or destroy the vinyl group. Typical vinyl-containing compounds are acrylamide, diacetone acrylamide, allylamine, etc. Mixtures of the resulting resins with polyester resins derived from a glycol and an unsaturated dibasic carboxylic acid are particularly useful. These resin mixtures are capable of being cured by free radical catalysts through the vinyl group to give improved properties. The resulting crosslinked products have excellent electrical properties and are particularly useful as molding compositions for encapsulating electrical parts, and also as binders in fiberreinforced plastics.
