    摘要: A thermoplastic resin composition comprising:(a) Alkylene aryl polyester copolymers having metal sulfonate units represented by the formula IA: ##STR1## or the formula IB:(M.sup.+n O.sub.3 S).sub.d --A--(OR"OH).sub.pwhere p=1-3, d=1-3, p+d=2-6, n=1-5, and A is an aryl group containing one or more aromatic rings where the sulfonate substituent is directly attached to an aryl ring, R" is a divalent alkyl group and the metal sulfonate group is bound to the polyester through ester linkages;(b) An essentially amorphous polycarbonate, polyester carbonate or polyarylate polymer containing recurring units of the formula II: ##STR2## wherein Ar is divalent aromatic residue of a dicarboxylic acid or mixture of dicarboxylic acids and Ar' is the divalent aromatic residue of a dihydric phenol or mixture of dihydric phenols. The composition may further comprise acidic phosphorus based quenchers, rubbery impact modifiers, mineral fillers or reinforcements.

    摘要: A data storage medium includes a substrate, a reflective metal layer, and a haze-prevention layer between the substrate and the reflective metal layer. The substrate includes an amorphous thermoplastic resin having a heat distortion temperature of at least about 140° C., a density less than 1.7 grams per milliliter, and an organic volatiles content less than 1,000 parts per million measured according to ASTM D4526. The haze-prevention layer includes a material having a volume resistivity of at least 1×10−4 ohm-centimeters and a tensile modulus of at least about 3×105 pounds per square inch. The data storage medium resists hazing of the reflective layer at elevated temperatures.

    摘要: A reflective article useful, for example, in automotive headlights includes a substrate, a reflective metal layer, and a haze-prevention layer between the substrate and the reflective metal layer. The substrate includes an amorphous thermoplastic resin having a heat distortion temperature of at least about 140° C., a density less than 1.7 grams per milliliter, and an organic volatiles content less than 1,000 parts per million measured according to ASTM D4526. The haze-prevention layer includes a material having a volume resistivity of at least 1×10−4 ohm-centimeters and a tensile modulus of at least about 3×105 pounds per square inch. The article resists hazing of the reflective layer at elevated temperatures.
