    Abstract: The present invention is a composition containing a polyester resin containing at least an alicyclic dicarboxylic acid component and an alicyclic diol component, and it is a polyester resin composition which satisfies that a glass transition temperature is 65°C or more and 90°C or less, a refractive index at sodium D line is 1.500 or more and' 1.570 or less, a titanium element content is 5 ppm or more and 500 ppm or less, a phosphorus element content is 50 ppm or more and 500 ppm or less and a gel fraction is 50% or less. By the present invention, it is possible to obtain a polyester resin composition having a low refractive index and photoelastic coefficient, and in which a thermally degraded foreign substance is reduced.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polyester which has excellent molding processability and can solve problems such as the staining of a spinneret, the elevation of filtration pressure and the breakage of fibers on the production of formed products such as fibers, films or bottles. SOLUTION: This method for producing a polyester comprises subjecting an aromatic dicarboxylic acid or its ester-forming derivative and a diol or its ester-forming derivative to an esterification reaction or a transesterification reaction and then polycondensing the product. Therein, the characteristics comprise using a dinuclear oxide containing titanium and silicon as main metal elements as a polycondensation catalyst and controlling the molar ratio (the molar ratio of the aromatic dicarboxylic acid or its ester-forming derivative to the diol or its ester-forming derivative) of the reaction system to 1.25 to 2.0 when the dinuclear oxide is added.

    Abstract: PROBLEM TO BE SOLVED: To obtain an antistatic polyester spun yarn having excellent antistatic property and dyeable to in all colors including color by spinning polyester staple containing specific antistatic core-sheath conjugate polyester fiber. SOLUTION: This polyester-based spun yarn is formed by blending at least 20 wt.% of an antistatic core-sheath type conjugate fiber comprising 0.2-3 wt.% of an antistatic agent obtained by mixing a polyetheramide with 1-10 wt.% based on the polyetheramide of RSO3M [R is an 8-15C alkyl; M is alkali (earth) metal and preferably Na] into a core component based on whole conjugate fiber, 0.6-10 wt.% of delustering agent and a weight ratio of the delustering agent to the antistatic agent is 0.3-2.0, and having

    Abstract: PURPOSE:To enhance the low temp. perforation properties or printing sharpness of stencil paper by adding aromatic dicarboxylic acid and the others as a main acid component and also adding aliphatic glycol having a specific number of carbon atoms and the others as a main glycol component and specifying an m.p. CONSTITUTION:Thermal screen printing stencil paper is produced by a perforation method using heat applying energy. In this case, as a film for the thermal screen printing stencil paper, a polyester film is used. Polyester constituting the film for the stencil paper consists of at least one acid component selected from aromatic dicarboxylic acid, aliphatic dicarboxylic acid and alicyclic dicarboxylic acid, 2-10C aliphatic glycol and/or 6-16C alicyclic glycol being a glycol component and a polyfunctional compd. component. The m.p. of polyester is set to 100-220 deg.C. By this constitution, perforation properties due to low heat applied energy and sharpness at the time of printing are respectively enhanced.
