| 摘要 |
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.
