摘要： Provided is a method for producing polyphenylene ether (PPE) having excellent mechanical properties, heat aging resistance, and color, and in which the content of impurities such as low molecular weight components and catalyst metal is low. The method for producing PPE includes: performing oxidative polymerization of a phenolic compound in a polymerization solution containing the phenolic compound, a catalyst, and an aromatic solvent to obtain a PPE mixed liquid; precipitating PPE to obtain a slurry containing particulate PPE through addition of a polar solvent to the PPE mixed liquid; solid-liquid separating the slurry to obtain wet PPE particles; washing the wet PPE particles to obtain PPE particles through at least one cycle of a washing and solid-liquid separation process in which washing is performed with a washing liquid containing an aromatic solvent and a polar solvent, and in which solid-liquid separation is performed; and drying the PPE particles.

摘要： The invention relates to a method for the purification of poly(arylene ethers) of formula (I) in which m=0 to 1.0, n=1.0-m, and Ar1, Ar2, Ar3 and Ar4 independently represent divalent arylene groups. The compound of formula (I) is produced in a first step 1, with a raw product being obtained by bringing a metal or ammonium salt of divalent dihydroxy derivatives of Ar1 or Ar3 into contact with one or more dihalogenated derivatives of Ar2 and/or Ar4, in the presence of a solvent LM1. A precipitate that is present, if appropriate, is separated (step B) so as to obtain a solution L which then undergoes a membrane filtration (step C).

摘要： A composition is prepared by oxidative copolymerization of specific amounts of 2,6-dimethylphenol, 2,3,6-trimethylphenol, and a hydroxyaryl-terminated polysiloxane. The composition exhibits an increased heat resistance relative to a corresponding composition prepared by copolymerizing 2,6-dimethylphenol and hydroxyaryl-terminated polysiloxane, without 2,3,6-trimethylphenol. The composition is useful as a flame-retardant additive in polymer compositions that require high heat resistance.
