  • Patent number: 5961902
    Abstract: A multilayer article such as a door trim board is fabricated by the steps of extruding melted resin layers (13m), (12m) and (11m) respectively forming a soft skin material (13), a foamed soft intermediate layer (12) and a base member (11) in the form of a multilayer resin sheet from a die-head (40) of an extruding machine, supply the extruded multilayer resin sheet to a molding machine in such a manner that the resin layer for the skin material is placed on a lower molding die of the molding machine and molding the resin layers in the form of the multilayer article. The resin layer for the skin material consists of thermoplastic elastomer, the resin layer for the intermediate layer consists of ethylenic copolymer copolymerized with ethylene and at least radical copolymerizable acid anhydride, and the resin layer for the base member consists of olefinic resin.

  • Patent number: 4929494
    Abstract: A laminate is disclosed, comprising substrates which are impregnated with a curable composition, laminated and cured, wherein the curable composition comprises (i) a curable prepolymer having a main chain consisting essentially of a random copolymer of a vinyl monomer and an acrylic or methacrylic monomer, and a side chain containing an acryloyl or methacryloyl group at the terminal, as a main component, and (ii) a crosslinkable vinyl monomer.

  • Patent number: 4735988
    Abstract: A propylene polymer composition comprising (A) a modified propylene polymer obtained by treating: (1) 100 parts by weight of a propylene polymer or a mixture of a propylene homopolymer and a ethylene-propylene copolymer rubber, with (2) 0.1 to 50 parts by weight of an organic compound having at least one unsaturated bond in the molecule and a hydroxyl group and (3) 0.01 to 20 parts by weight of an organic peroxide; and (B) a propylene polymer, wherein content of the component (A) in the composition is 5 to 50% by weight. This composition may further contain one or more of (C) an amorphous ethylene-propylene copolymer having a propylene content of 20% to 50% by weight and a Mooney viscosity ML.sub.1+4 at 100.degree. C. of 20 to 100, (D) a high-density ethylene copolymer having a density of 0.935 g/cm.sup.3 or more, (E) a linear low-density ethylene copolymer having a density of not less than 0.900 g/cm.sup.3 but less than 0.935 g/cm.sup.2, a melting point of 106.degree. C. to 130 C., a melt flow rate of 0.
