Abstract: PURPOSE:To obtain the titled yarn having excellent adhesivity to matrix resin without damaging high modulus and high strength, by oxidizing poly-para- phenylene benzothiazole yarn in a gas phase and modifying the main structure unit thereof. CONSTITUTION:Poly-para-phenylene benzothiazole (hereinafter abbreviate PBT) yarn consisting of a unit shown by formula I is oxidized in a gas phase or in liquid phase and >=5mol% unit shown by formula I is modified into a unit shown by formula II (X and Y are 0-2 integer with the proviso that a case where both X and Y are O is omitted) to give the aimed yarn. PBT of raw material, for example, is obtained by subjecting 2,5-dithiol-1,4 phenylenediaminediammonium chloride and terephthalic acid to polycondensation in a polyphosphoric acid solvent at high temperature. In oxidizing PBT in a liquid phase, an oxidizing agent of organic peroxide type such as peracetic acid, etc., is preferably used.

Abstract: PURPOSE: To obtain the film for thermal stencil paper, which is excellent in stretching stability and has favorable planeness with small thickness fluctuation by a method wherein a specified component is copolymerized with a polyester so as to make the percentage of the widthwise thickness fluctuation not more than a specified value. CONSTITUTION: This film for thermal stencil paper is made of a copolymerized polyester containing 0.5-50mol.% aliphatic dicarboxylic acid as a dicarboxylic acid component. By copolymerizing the aliphatic dicarboxylic acid with a polymer, the stretching stability of the resultant copolymerizate is improved and, at the same time, its planeness becomes favorable, resulting in settling uneven printing. Further, the favorable widthwise thickness fluctuation of the polyester film is not more than 20%. If the fluctuation exceeds 20%, the laminating properties between porous support and the film is lowered and the perforating properties of the film is deteriorated, resulting in developing uneven printing.

Abstract: PURPOSE: To provide a polymer coated metal laminate of superior compatibility of molding properties, particularly resistance to impact and taste characteristics by coating a layer, in which polyester A composed of ethylene terephthalate or ethylene isophthalate of specified melting point as main component and thermoplastic elastomer are blended together by a specified weight ratio, with extruded laminate. CONSTITUTION: A polymer coated metal laminate is formed by coating a layer I constituted of polyester A composed of ethylene terephthalate of ethylene isophthalate having melting point of 140-245 deg.C as main component and thermoplastic elastomer blended together by the ratio of 70:30-98:2 by the weight ratio. Resistance to impact is good even when a number of heat histories such as heat treatment in the can manufacturing process, retort treatment after the can manufacturing process and the like are applied after extrusion laminating to the metal and mold, and molding and can manufacturing are carried out by mixing thermoplastic elastomer of adequate amount i0 polyester having specified melting point. Not only the compatibility of resistance to impact with taste characteristics but also resistance to impact can be improved to a large extent by the above-said effect.
