  • Patent number: 9725591
    Abstract: The present invention relates to a reinforced resin composition for plating bases having excellent moldability, mechanical strengths, and plating ability, as well as being capable of improving the surface appearance of the molded article after plating. The reinforced resin composition for plating bases of the present invention includes: graft copolymer (A) in which a graft chain (A2) is grafted to a rubber polymer (A1) a matrix polymer (B) which includes one or more types of polymers selected from the group consisting of a vinyl-based copolymer (B-1), a polycarbonate resin (B-2), and a polyester resin (B-3); an inorganic filler (D); and a glycidyl ether unit-containing polymer (E). The content of the rubber polymer (A1) is from 5 to 25% by mass, relative to 100% by mass of the total amount of the component of (A) and the component of the matrix polymer (B).
    Type: Grant
    Filed: December 26, 2008
    Date of Patent: August 8, 2017

  • Publication number: 20100273922
    Abstract: The present invention relates to a reinforced thermoplastic resin composition having excellent moldability, processability, and mechanical strengths, as well as being capable of improving the drop impact resistance (surface impact strength determined by a falling ball test). The reinforced thermoplastic resin composition of the present invention includes 10 to 60% by mass of a graft copolymer (A) having a graft chain (A2) grafted to a rubber polymer (A1); 40 to 90% by mass of a matrix polymer (B) which includes one or more types of polymers selected from the group consisting of a vinyl-based copolymer (B-1), a polycarbonate resin (B-2), and a polyester resin (B-3); 0.1 to 50 parts by mass of an inorganic filler (D) and 0.5 to 20 parts by mass of a glycidyl ether unit-containing polymer (E) having a mass average molecular weight of 3,000 to 200,000.

  • Patent number: 4109038
    Abstract: A suede-like raised woven fabric which comprises: warp yarns; weft yarns, each being a single twist filament yarn or a loopy textured filament yarn consisting of a bundle of fine fibers; and an elastic polymer applied to the fabric. The bundle of fine fibers consists of a raised portion having an average monofilament denier of from 0.05 to 0.4 and an unraised portion having an average monofilament denier of above 0.4 but not exceeding 0.8.

  • Patent number: 4051287
    Abstract: A suede-like or deer skin-like raised woven or knitted fabric having at least one raised surface is produced by providing a woven or knitted fabric using a yarn consisting of synthetic hollow composite fibers each composed of two or more fiber-forming polyester constituents and two or more fiber-forming polyamide constituents and having a hollow space surrounded by the polyamide and polyester constituents which are arranged alternately with each other and adhered to each other side-by-side so as to form a tube-shaped body, and raising a surface of the fabric while allowing the hollow composite fibers located in at least the raised surface portion of the fabric to be divided into numerous very fine fibrils consisting of said polyester and polyamide constituents.

  • Patent number: 3998988
    Abstract: A conjugate fiber of a thermoplastic synthetic organic polymer composed of a high melting polymer component and a low melting polymer component, said low melting polymer component having a melting point at least 40.degree. C. lower than that of the high melting polymer component, and having adhered to its surface finely divided particles of an adsorbent. The fiber is a good filter having reduced pressure loss and increased adsorbing power. Fibrous materials and articles are made from these conjugate fibers.
