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.
