Abstract: PURPOSE:To obtain a polyester composition giving a molded article having excellent slipperiness, abrasion resistance, etc., and suitable for fiber, film, etc., by using composite inert particles having a specific shape as a component. CONSTITUTION:The objective polyester composition is produced by compounding a polyester with 0.005-10wt.% (preferably 0.01-3wt.%) of composite inert particles having an average particle diameter of 0.05-5mum (preferably 0.1-2mum) and produced e.g. by coating a core particle charged with positive or negative charge (e.g. silica, titanium oxide or calcium carbonate) with fine particles (e.g. silica or alumina) charged with opposite charge and having an average particle diameter corresponding to 1/(1,000-10) [preferably 1/(500-20)] of the diameter of the core particle. The ratio of the coating thickness to the diameter of the core particle is 1/1000-10, preferably 1/500-1.

Abstract: PURPOSE:To obtain a composition which can give a film or a fiber excellent in lubricity and abrasion resistance, by dispersing cerium oxide particles in a thermoplastic polyester. CONSTITUTION:A thermoplastic polyester composition is formed by homogeneously and finely dispersing cerium oxide particles in a thermoplastic polyester. Although the cerium oxide particles used may be particles of cerium (III) oxide (Ce2O3) or cerium (IV) oxide (CeO2), CeO2 particles are more desirable. The mean particle diameter of the cerium oxide particles used is desirably 0.1-3.0Xm when it is used in a film or a fiber. When this diameter is below 0.01mum, the lubricity of a molding is not sufficient, while a diameter above 5mum is undesirable because large protrusions are formed on the molding. The content of the cerium oxide is desirably 0.01-5wt.% based on the polyester.

Abstract: PURPOSE:To enable ester interchange reaction of a dicarboxylic acid dialkyl ester with an alkylene glycol in short time and high stability, by performing he reaction in a reaction system under a pressure higher than atmospheric pressure and discharging the alkylene glycol out of the system. CONSTITUTION:Dialkyl ester of 1,2-bis(chlorophenoxy)ethane-4,4'-dicarboxylic acid is subjected to ester interchange reaction with an alkylene glycol under a pressure higher than atmospheric pressure, preferably under 0.1-3kg/cm G pressure. After the completion of the reaction, the pressure of the reaction system is lowered preferably to G and remaining alkylene glycol is discharged from the system to obtain bis(beta-hydroxyalkyl)-1,2-bis (chlorophenoxy)ethane-4,4'-dica-rboxyl ate or its oligomer.

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).
