    摘要: A process for producing a phosphonitrilic acid ester. The process comprises using a specific compound as a catalyst to react phosphonitrile dichloride with at least one member selected among phenol compounds and/or alcohol compounds in the presence of a reaction solvent. Alternatively, the process comprises reacting a liquid reaction mixture obtained in a first stage with at least one member selected among phenol compounds and/or alcohol compounds without isolating phosphonitrile dichloride from the mixture.

    摘要: A novel curable polyphenylene ether resin composition is disclosed, which comprises (a) a curable polyphenylene ether resin having at least one group selected from the group consisting of an allyl group and a propargyl group and (b) at least one cyanurate. The resin composition has excellent storage stability, film-forming properties and melt moldability. If desired, a fire retardant, optionally together with an antimony-containing auxiliary fire retardant, and/or a reinforcement is incorporated into the resin composition in order to improve the fire retardance and mechanical properties of the resin composition, respectively. By curing the resin composition, a cured polyphenylene ether resin composition comprising a chloroform nonextractable polyphenylene ether resin component and a chloroform extractable, polyphenylene ether-containing component is obtained, which has excellent chemical resistance, electrical properties, dimensional stability and heat resistance. A laminate or composite structure comprising the cured polyphenylene ether resin composition and a metallic foil and/or a metallic substrate provides advantageous mechanical and electronic components.

    摘要: A novel cured polyphenylene ether resin is disclosed comprising a chloroform nonextractable polyphenylene ether and a chloroform extractable polyphenylene ether. By subjecting the resin to pyrolysis gas chromatography, the resin is decomposed to form 3,5-dimethylphenol specifically. The chloroform extractable polyphenylene ether is contained in the resin in an amount of 0.01 to 20% by weight and comprises polyphenylene ether units substituted by an alkenyl group and/or an alkynyl group. The novel cured polyphenylene ether resin has excellent mechanical properties, electrical properties, heat resistance and chemical resistance. The cured polyphexylene ether resin is prepared by curing a novel curable polyphenylene ether resin comprising polyphenylene ether units substituted with an alkenyl groups and/or an alkynyl groups at a specific average substitution degree. The novel curable polyphenylene ether resin has not only excellent mechanical properties and desired electric properties such as a low dielectric constant and a low dielectric dissipation factor, but also excellent melt processability and storage properties.
