Thermoplastic polyester composition and film made therefrom

摘要

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); another thermoplastic polyester composition comprising the thermoplastic polyester (A) and a mixture (C) of at least two kinds of aluminum oxide particles different from each other in crystal structure; and films made from these compositions. The compositions can provide films excellent in slipperiness, wear resistance, and scratch resistance in repeated high-speed traveling.
