    摘要: This invention relates to novel copolymers derived from diphenyl ether, terephthalic acid derivative and a third monomer of the formula ##STR1## where n=1 or 2. The copolymers can be prepared by Friedel-Crafts polymerization. Preferred copolymers are derived from diphenyl ether, terephthaloyl chloride, and 1,4-diphenoxybenzene.

    摘要: Substantially pure p-phenoxybenzoyl compounds are prepared by reacting diphenyl ether and an appropriate acyl compound in the presence of hydrogen fluoride. The resulting p-phenoxyaryl alkyl ketone can be converted into p-phenoxybenzoic acid or salts thereof, p-phenoxybenzoyl halide or lower alkyl p-phenoxybenzoate for use preparing homo- and copolymers containing a p-phenoxybenzoyl repeating unit.
