    摘要: A three dimensional copolymer network of polyphenylene ether segments and styrenic resins such as styrene/acrylonitrile copolymers provide articles of high heat reesistance and dielectric properties suitable for use in electronic components. Methods for preparing the copolymers employ polyphenylene ether polymers with end caps having at least one pair of unsaturated aliphatic carbon atoms, i.e. carbon-carbon double bond, and polymerize styrene monomers and acrylonitrile monomers or styrene/acrylonitrile copolymers or both in the presence of these polyphenylene ether polymers.
