  • Patent number: 8334344
    Abstract: The sliding material is obtainable by extrusion of a raw material containing an olefin-based polymer and a silicone compound as the essential components. A part of the olefin-based polymer forms a crosslinked material in the sliding material. The crosslinked material forms domains to disperse in the sliding material so as to prevent uneven distribution of the silicone compound in the extrusion direction. The residual fraction of hot xylene reflux of the sliding material is in a range from 33 to 75% by weight based on the total weight of the sliding material, and the content of the silicone compound based on the total weight of the sliding material is in a range from 5 to 35% by weight.
    Type: Grant

  • Patent number: 4701279
    Abstract: An anisotropically electroconductive adhesive which is solid at room temperature, preferably, in the form of a film is prepared by dispersing conductive particles such as metal particles and the like in a thermoplastic insulating adhesive composition comprising an unvulcanized thermoplastic elastomer such as a styrene-based elastomer and a crosslinked synthetic rubber and/or thermoplastic elastomer as a vulcanizate derived from an unvulcanized synthetic rubber or thermoplastic elastomer using a vulcanizing agent such as organic peroxides. The conductive adhesive is useful in adhesively bonding, for example, two electronic circuit boards without disadvantages of instability of the electric resistance, inconvenience in the application and so on.
