Curable compositions comprising a polyphenylene ether resin free of substituents which inhibit free radicals are combined with a polyvinyl unsaturated compound, such as poly(bisphenol-A fumarate) or divinyl benzene, and, optionally liquid polymerizable unsaturated monovinyl monomers, such as styrene, and cured with an optional catalyst to produce crosslinked interpolymers more rapidly than in the prior art. Before curing, the compositions can be combined with flame retardants, reinforcing fillers and/or impact modifiers.
由不含抑制自由基的取代基的聚苯醚树脂组成的可固化组合物与聚乙烯不饱和化合物(如聚(双酚 A 富马酸酯)或二乙烯基苯)以及可选择的液态可聚合不饱和单乙烯基单体(如苯乙烯)相结合,并在可选择的催化剂作用下固化,从而比现有技术更快地生成交联互聚合物。 在固化前,组合物可与阻燃剂、增强填料和/或抗冲改性剂相结合。
