摘要

PCT No. PCT/JP93/00073 Sec. 371 Date Sep. 22, 1993 Sec. 102(e) Date Sep. 22, 1993 PCT Filed Jan. 27, 1993 PCT Pub. No. WO93/15145 PCT Pub. Date Aug. 5, 1993Disclosed 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.
