Abstract: A solution of a poly(phenylene ether) copolymer derived from 2-methyl-6-phenylphenol and a dihydric phenol in a non-halogenated solvent is useful in curable compositions. The copolymer has less than 0.5 weight percent monohydric phenols having identical substituents in the 2- and 6-positions of the phenolic ring, and an absolute number average molecular weight of 1,000 to 10,000 grams/mole.
