Abstract: According to the present invention there is provided a polyester composition comprising an aromatic polyester having copolymerized therein a compound containing at least one sulfonic acid group or sulfonic acid metal salt group, and crosslinked polymer particles, preferably crosslinked polymer particles coated with a water-soluble polymer. The particles are incorporated in a slurried state into the polymer. There is also provided a laminate film containing the polymer with the particles thus incorporated therein. The polyester composition is superior in uniform dispersibility of the particles, re-agglomeratin does not occur in melt-storage for a long time, and films formed using the polyester composition are superior in traveling performance and abrasion resistance.

Abstract: A polyester fiber comprises a hygroscopic polyester composition which contains 1 to 20 percent by weight of hygroscopic silica-based inorganic particles in which the average diameter, the specific surface area, the micropore volume, and the hygroscopic parameter DELTA MR are within specified ranges. This hygroscopic fiber is suitable for clothes which require comfortableness.

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.
