Abstract: A method for reducing outgassing of a polyester composed of repeat units derived from 1,4-butanediol is melt blending the polyester with 0.2 to 2 weight percent water, based on the weight of the polyester. In addition to water, the polyester can also be blended with 0.01 to 0.5 weight percent of a quencher. The method results in formation of a polyester composition which exhibits reduced outgassing, and is suitable for molding into articles, for example an automotive headlight reflector or bezel.

Abstract: A composition includes 100 parts by weight of poly(alkylene terephthalate) and 0.01 to 2 part by weight of a compound represented by Formula (1), a partially saponified derivative thereof, or a combination thereof, (1) wherein R1, R2, and n are defined herein. The composition, which excludes copolymers of an unsubstituted or substituted styrene and an unsaturated nitrile, is useful for molding articles with very smooth surfaces. For example, the composition can be used to mold directly-metallizable substrates for automotive headlight reflectors and bezels.

Abstract: A composition includes specific amounts of a poly(alkylene terephthalate) and an epoxy compound having a weight average molecular weight of at least (500) daltons, and an epoxy equivalent weight of at least (400) grams per equivalent. The composition exhibits high melt flow, and articles molded from the composition exhibit reduced high-temperature outgassing compared to corresponding compounds without the epoxy compound. The composition is suitable for molding directly metallizable reflectors and bezels for automotive headlights.
