Eine härtbare Polyphenylenetherharzzusammensetzung und eine daraus herstellbare gehärtete Harzzusammensetzung.

摘要

A novel curable polyphenylene ether resin composition caontains (a) a curable polyphenylene ether resin containing at least a reaction product of a polyphenylene ether with an unsaturated carboxylic acid or an acid anhydride, (b) at least one cyanurate selected from the group consisting of triallyl isocyanurate and triallyl cyanurate, optionally (c) a resin composition comprising an epoxy resin and a curing agent and/or (d) a compound having at least one unsaturated double bond and at least one epoxy group and/or (e) a reinforcement material. The resin composition has excellent film-forming properties, resin flowability in pressing and storage stability. A cured polyphenylene ether resin composition obtained by curing the curable polyphenylene ether resin composition has excellent chemical resistance, heat resistance, dielectric properties and dimensional stability.
