摘要： In the production of polyphenylene ethers by oxidative polycondensation of phenols in the presence of a complex catalyst, an aminocarboxylic acid derivative and a reducing agent are simultaneously added to the reaction mixture when the resulting polyphenylene ether has attained the desired degree of polymerization, thereby to terminate the polymerization and simultaneously purify the reaction mixture. Hence, a stable purified polymer can be obtained.

摘要： Polyphenylene oxides, self-condensation products of phenols, are produced through oxidative coupling by employing a novel catalyst system which comprises a copper compound, an iodine compound and tertiary diamine which is capable of forming a stable chelate ring with the copper compound.According to this invention, copper compounds, which hitherto have been considered to be unsuitable for using with tertiary amines, act with excellent performance as a component of the catalyst.
