Abstract: A poly(phenylene ether) copolymer of 2-methyl-6-phenylphenol and a dihydric phenol having an absolute number average molecular weight of 1,000 to 10,000 grams/mole is made by polymerization of 2-methyl-6-phenylphenol and a dihydric phenol in the presence of molecular oxygen, a polymerization catalyst comprising a metal ion and at least one amine ligand, and a solvent composed of at least 95 weight percent of a C 1 -C 3 alcohol selected from methanol, ethanol, 1-propanol, and 2-propanol. The poly(phenylene ether) copolymer can be, for example, a copolymer of 2-methyl-6-phenylphenol, 2,2-bis(3,5-dimethyl-4-hydroxyphenol)propane, and optionally 2,6-dimethylphenol. The poly(phenylene ether) copolymer finds utility in curable compositions, cured compositions, and articles.

Abstract: An improved method for making a poly(phenylene ether) polymer comprises oxidative polymerization of at least one phenol of the general structure described herein, in the presence of a non-polar solvent, a liquid oxidant, an iron complex, an amine ligand, and a phase transfer catalyst, and in the absence of added water other than any water present in the liquid oxidant and phase transfer catalyst. The method is applicable to phenols that include 2,6-dimethylphenol, 2,4,6-trimethylphenol, 2-methyl-6-phenylphenol, 2,6-diphenylphenol, 2-allyl-6-methylphenol, o -phenylphenol, m -phenylphenol, or combination thereof. The iron complex can be Fe(II)(salen), Fe(III)(salen)Cl, [Fe(III)(salen)] 2 O, or combination thereof, and the liquid oxidant can be aqueous hydrogen peroxide. A poly(phenylene ether) made by the method is also disclosed.
