THERMOPLASTIC POLYESTER COMPOSITION AND FILM MADE THEREFROM

摘要

Disclosed are a thermoplastic polyester composition comprising a thermoplastic polyester (A) prepared from an acid component mainly comprising an aromatic dicarboxylic acid and a glycol component mainly comprising an aliphatic glycol and .theta. type aluminum oxide particles (B); a thermoplastic polyester composition comprising the thermoplastic polyester (A) and a mixture (C) of two or more kinds of aluminum oxide particles different from each other in crystal structure; and films made from these compositions. Particularly, the films formed from the compositions can have excellent slipping property, abrasion resistance, and scratch resistance in repeated high-speed running.
