Abstract: A thermoplastic polyester composition comprises a thermoplastic polyester prepared from an acid component mainly comprising an aromatic dicarboxylic acid and a glycol component mainly comprising an aliphatic glycol and a particulate mixture of two or more aluminium oxide components different from each other in crystal structure types, one of which is the &thetas;-type crystal structure. Since films formed from the compositions can have excellent slipping property, abrasion resistance and scratch resistance in repeated high-speed running, they are particularly suitable as substrates in magnetic recording media.

Abstract: The present invention relates to a polyester composition, comprising 0.5 to 300 ppm, as titanium atoms, of a compound oxide (A) containing titanium as an essential element and also containing a metal element selected from a group consisting of aluminum, zirconium, germanium, tin and silicon, and 0.001 to 40 wt% of particles with an average particle size of 0.01 to 10 mu m, and also to a method of production thereof, and a film composed of said polyester composition. The polyester composition of the present invention is excellent in moldability and heat resistance and solves such problems as die contamination, filtration pressure rise and yarn breaking in the production of such moldings as fibers, films and bottles. Furthermore, the polyester film of the present invention is suitable for packaging, being excellent in taste property and long-term storage quality, and can be suitably used for packaging materials, above all for being formed, especially for being laminated and formed with a substrate such as paper, nonwoven fabric or metal, to make containers, etc.

Abstract: This invention relates to a polyester composition containing particles of a cross-linked polymer having an ester bond in the principal chain. These particles have excellent affinity for polyester. Accordingly, in a film molded from polyester containing these particles, the particles hardly come off during a high-speed travelling of the film, and flaws ascribed to the particles also hardly occur on the film surface. Therefore, the deterioration of a film due to the occurrence of white powder thereon which is ascribed to the falling of the particles, which has posed problems when various kinds of particles were added, and due to the flaws on a magnetic surface can be prevented. Moreover, the contamination of the film manufacturing processes can be prevented, and the film thus obtained can be used suitably as, especially, magnetic tape.
