    Abstract: The present invention relates to substantially pure poly(arylene ether), e.g. purities exceeding about 99 %, and to a method for making the same. The method which eliminates multiple rinses with a reagent includes removing the catalyst from the polymerization mixture by mixing the polymerization mixture with a complexing reagent and liquid/liquid centrifuging the multiphase mixture. Water is then added to the polymer phase prior to a subsequent liquid/liquid centrifuge process. Once the catalyst has been sufficiently removed, the polymer can be concentrated in a flash vessel (which is not heated) by introducing a heated polymer phase to the vessel at a high pressure and quickly reducing the pressure. The concentrated polymer can then be introduced to an extruder to produce the high purity polymer. Due to the introduction of low molecular weight poly(arylene ether) at the intake zone of the extruder to produce the high purity polymer. Due to the introduction of low molecular weight poly(arylene ether) at the intake zone of the extruder, essentially pure poly(arylene ether) can be isolated by this process. By combining the extruder process with an underwater pelletizer, thus providing extremely rapid cooling of the polymer melt when it exits the extruder and contacts air, much better color and lower amount of blacks specs in the final products is obtained.

    Abstract translation: 本发明涉及基本上纯的聚（亚芳基醚），例如 纯度超过99％，以及其制造方法。 用试剂消除多次冲洗的方法包括通过将聚合混合物与络合试剂和离心多相混合物的液/液混合来从聚合混合物中除去催化剂。 然后在随后的液/液离心分离工艺之前，将水加入到聚合物相中。 一旦催化剂已被充分除去，聚合物可以通过在高压下将加热的聚合物相引入容器而快速降低压力而将其浓缩在闪蒸容器（其不加热）中。 然后将浓缩的聚合物引入挤出机以制备高纯度聚合物。 由于在挤出机的入口区域引入低分子量聚（亚芳基醚）以产生高纯度聚合物。 由于在挤出机的入口区域引入低分子量聚（亚芳基醚），所以可以通过该方法分离出基本上纯的聚（亚芳基醚）。 通过将挤出机工艺与水下造粒机组合，从而在聚合物熔体离开挤出机并接触空气时提供非常快速的冷却，从而获得最终产品中更好的颜色和更少的黑色规格。

    Abstract: PROBLEM TO BE SOLVED: To control the formation of the subject alkylated phenol, by transalkylating an alkylphenol with another phenol in the presence of a catalyst of a metal oxide at a specific temperature. SOLUTION: One or more alkyl groups at the ortho- or para-position based on the hydroxyl group of an alkylated phenol are removed or rearranged in the presence of a catalyst containing an oxide of a metal selected from the group consisting of Mg, Zn, Fe, V, Ce, Mn or their combination at 400-675 deg.C to control the formation of a highly alkylated phenol during the reaction. The alkylated phenol contains a 1-6C alkyl group. Preferably the reaction contains an oxidizing atmosphere selected from the group consisting of air and oxygen. The flow velocity of the alkylated phenol is preferably in the range of 0.1-3.0 g/hour/catalyst gram.

    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.
