Abstract
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.
