POLY (ETHYLENE TEREPHTHALATE) COPOLYMERS WITH HALOGENATED TEREPHTHALIC ACIDS
Sen'i Gakkaishi, 1981 Poly (ethylene terephthalate) copolymers were prepared by substitution up to 40 mol% of diacid comonomers: 2, 5-dichloroterephthalic acid (TCl2) and 2, 5-dibromoterephthalic acid (TBr2). ηsp/C of the copolymers does not depend on the comonomer content. Melting point depression shows that copolymers with TCl2 and TBr2 are non-isomorphous.
