Abstract: PROBLEM TO BE SOLVED: To provide a resin composition having characteristics of both resin and particles and having good moldability and heat resistance in its molding for producing a molded product, and to provide a film reduced in virgin material content and so having a low environmental loading and intended for hard-to- recycle magnetic tapes, ribbon tapes, paper, abrasive paper and the like. SOLUTION: This resin composition is characterized by comprising 10-60 wt.% resin and 40-90 wt.% inorganic particles compose mainly of silicon. The film is characterized by being made from the resin composition.

Abstract: PROBLEM TO BE SOLVED: To provide a polyester composition and a polyester film excellent in surface properties, mechanical properties, a traveling property and heat resistance. SOLUTION: The polyester film is obtained by forming a coating layer having 0.005-50 μm thickness and containing particles having ≤100 nm average short diameter (ASP) and 20-1,000 particle diameter ratio (ALP/ASP) of average long diameter (ALP) to the ASP on at least one surface.

Abstract: PROBLEM TO BE SOLVED: To provide a polyester resin composition having various performances such as a productivity, an electric insulation, a thermal resistance, and to provide a film. SOLUTION: The polyester is composed of particles containing at least two kinds of elements selected from typical elements belonging to the IV or V period in the periodic table of elements. When the particles are added to the polyester to form the polyester resin composition, R and R0 satisfy the relation: R/R0≥1.1 (wherein R0 is a relative dielectric constant of the polyester before the particles are added and R is the relative dielectric constant of the polyester after the particles are added).

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.

Abstract: PROBLEM TO BE SOLVED: To provide a polyester film almost free from coarse projection and defects, and excellent in surface properties, oligomer deposition-inhibiting properties and productivity. SOLUTION: The polyester composition comprises a 10-30C higher fatty acid component, a 10-30C higher aliphatic alcohol component, or an ester compound thereof in an amount of 0.1-10 wt.% in total and gives measurements of molecular weight polydispersity by the GPC simultaneously satisfying following equations (1) and (2); Mw/Mn>4.4 (1), Mz/Mw>2.0 (2), wherein Mw is a weight-average mol.wt.; Mn is a number-average mol.wt.; and Mz is a z- average mol.wt. The polyester composition gives a polyester film excellent in oligomer deposition-inhibiting properties and is very suitably employed for film applications, as a film for a magnetic tape in particular.
