Abstract: The invention relates to methods of capping poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g. More particularly, the methods comprise capping a poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g in a solvent to produce a capped poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g and isolating the capped poly(phenylene ether) resin by removal of the solvent, preferably in a process other than precipitation. The invention also relates to the capped poly(phenylene ether) resin having an intrinsic viscosity between 0.05 and 0.35 dl/g.

Abstract: Poly(arylene ether) resins having intrinsic viscosities greater than about 0.8 dL/g are produced in the reaction of a phenol with oxygen in the presence of an organic solvent and a metal complex catalyst, the phenol concentration being about 5 to about 15 weight percent of the sum of phenol and solvent, and the molar ratio of metal in the metal complex catalyst to the phenol being about 1:100 to about 1:200.

Inventor： BRAAT J , DE JONGH RENE , LISKA JURAJ
IPC: C08G65/48
Abstract: The invention relates to a novel process for preparing functionalized PPE, the process comprising oxidative coupling in a reaction solution at least one monovalent phenol species using an oxygen containing gas and a complex metal catalyst to produce a PPE; and functionalizing the PPE prior to and/or during at least one isolation step for devolatilization of the reaction solvent. The invention also relates to the polyphenylene ether resin made by the process as well as blends and articles containing the polyphenylene ether resin made by the process.
