Abstract: PURPOSE:To obtain a composition having small voids in molding into films and yarns, excellent slipperiness and shaving resistance, comprising particles subjected to surface treatment with a specific polyester and a thermoplastic polyester. CONSTITUTION:Particles subjected to surface treatment with a polyester which is a polyester comprising a dicarboxylic acid and a glycol component wherein >=60mol% total dicarboxylic acid components of the polyester segment are aromatic dicarboxylic acids and 10-40mol% total dicarboxylic acid components are dicarboxylic acids containing sulfonic acid or an alkali metal salt thereof and a glycol component is an aliphatic or alicyclic glycol, b are blended with a thermoplastic polyester. Calcium carbonate is preferably used as the particles which has preferably 0.1-3mum average particle diameter in the case of aiming a magnetic recording medium.

Abstract: PURPOSE:To provide a polyester composition which can give a molding, such as a film or a fiber, possessing both easy slidability and abrasion resistance, by adding a specified amount of specified silicone rubber particles to a polyester. CONSTITUTION:Silicone rubber particles of a mean particle diameter of 0.01-5mum, having structural units of the formula (wherein R1, R2 and R3 are each methyl, ethyl or phenyl, and m:n=5:95-80:20) are prepared. In the production of a polyester (e.g., polyethylene terephthalate), the prepared particles are added to the reaction system to produce a polyester containing 0.005-15wt.% silicone rubber particles. The obtained polyester composition is melt-molded into a film, and this film is biaxially oriented and heat-set to produce a biaxially oriented polyester film excellent in lubricity and chipping resistance and suitable for, e.g., a magnetic tape.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polyester composition whereby the improvement in heat resistance of a polyester composition and the improvement in productivity accompanying to catalyst recovery can be achieved by removing a metal from the composition. SOLUTION: In a polyester production process containing an esterification step using an esterification catalyst and a polycondensation step using a polycondensation catalyst, a polyester composition is produced by separating and recovering the esterification catalyst and/or the polycondensation catalyst by adding a ligand, provided the ligand contains at least one kind of donor atom which can be coordinated with a metal or a metal ion and is selected from the group consisting of nitrogen, sulfur, and oxygen.
