METHOD OF FORMING HIGH MOLECULAR WEIGHT POLY(PHENYLENE ETHER), POLY(PHENYLENE ETHER) FORMED THEREBY, AND FIBER AND ARTICLE COMPRISING THE POLY(PHENYLENE ETHER)
METHOD OF FORMING HIGH MOLECULAR WEIGHT POLY(PHENYLENE ETHER), POLY(PHENYLENE ETHER) FORMED THEREBY, AND FIBER AND ARTICLE COMPRISING THE POLY(PHENYLENE ETHER)
A poly(phenylene ether) can be prepared by a method that includes reacting 2,6-dimethylphenol in the presence of toluene, oxygen, copper ion, bromide ion, and N,N′-di-tert-butylethylenediamine to form a poly(phenylene ether). The mole ratio of 2,6-dimethylphenol to copper ion is 160:1 to 300:1, the mole ratio of N,N′-di-tert-butylethylenediamine to copper ion is 1.5:1 to 3:1, and the mole ratio of atomic oxygen to 2,6-dimethylphenol is 0.9:1 to 1.5:1. The process can produce poly(phenylene ether) having a high molecular weight and a high incorporated amine content.
