摘要： A method of purifying a poly(phenylene ether) is described. The method includes mixing a poly(phenylene ether) solution comprising a poly(phenylene ether) and a poly(phenylene ether) solvent with first washing solvents including a C1-C4 alkanol and water to form a first liquid phase including poly(phenylene ether) and poly(phenylene ether) solvent, and a second liquid phase comprising C1-C4 alkanol and water, and separating the first liquid phase from the second liquid phase. The first and second liquid phases combined comprise about 60 to about 95 weight percent poly(phenylene ether) solvent, about 4 to about 32 weight percent C1-C4 alkanol, and about 1 to about 36 weight percent water. When optionally combined with evaporative removal of the poly(phenylene ether) solvent, the method reduces C1-C4 alkanol usage compared to the antisolvent precipitation method, and it produces poly(phenylene ether) having reduced catalyst metal ion residue and reduced color.

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.
