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.
