Title: POLY(PHENYLENE ETHER) COPOLYMER AND METHOD OF MAKING
Abstract:
A poly(phenylene ether) copolymer comprising about 5 to 40 mole percent repeat units derived from 2-phenylphenol and 60 to about 95 mole percent repeat units derived from 2,6-dimethylphenol, wherein the poly(phenylene ether) copolymer has a weight average molecular weight of at least 8,000 atomic mass units, is disclosed. Also disclosed is a method of preparing the poly(phenylene ether) copolymer, the method comprising oxidatively copolymerizing a monomer mixture comprising about 5 to 40 mole percent 2-phenylphenol and about 60 to about 95 mole percent 2,6-dimethylphenol in the presence of a solvent, molecular oxygen, and a polymerization catalyst comprising a metal ion and at least one amine ligand to form a solution of the poly(phenylene ether) copolymer in the solvent, wherein a ratio of total moles of 2-phenylphenol and 2,6-dimethylphenol to moles of metal ion is about 10:1 to about 1200:1.
