Abstract: A poly(2,6-dimethyl-1,4-phenylene ether) prepared using a morpholine-containing polymerization catalyst has a monomodal molecular weight distribution with a reduced content of very high molecular weight species. It also exhibits increased morpholine incorporation in the high molecular weight fraction. Compared to commercially available poly(2,6-dimethyl-1,4-phenylene ether) prepared using a di-n-butylamine-containing polymerization catalyst, the poly(2,6-dimethyl-1,4-phenylene ether) of the invention exhibits reduced odor. Compared to other poly(2,6-dimethyl-1,4-phenylene ether) prepared using a morpholine-containing polymerization catalyst, the poly(2,6-dimethyl-1,4-phenylene ether) of the invention exhibits improved molecular weight build during compounding and improved compatibilization with polyamides.

Abstract translation: 使用含吗啉的聚合催化剂制备的聚（2,6-二甲基-1,4-亚苯基醚）具有单分子分子量分布，具有非常高的分子量物质含量降低。 它还表现出高分子量级分中增加的吗啉掺入。 与使用含有二正丁胺的聚合催化剂制备的市售聚（2,6-二甲基-1,4-亚苯基醚）相比，聚（2,6-二甲基-1,4-亚苯基醚） 发明显示减少的气味。 与使用含吗啉的聚合催化剂制备的其它聚（2,6-二甲基-1,4-亚苯基醚）相比，本发明的聚（2,6-二甲基-1,4-亚苯基醚）表现出改善的分子量 在复合期间建立并改善与聚酰胺的相容性。
