  • Method of reducing static electricity in plastic compositions and antistatic compositions
    Patent number: 4085087
    Abstract: A method of reducing the electrostatic charge aquired by a plastic composition by incorporating therein an antistatically effective amount of a mixed oxide of phosphorus and one or more metals selected from the group consisting of silicon, aluminum, titanium and iron, said mixed oxide having been prepared by flame hydrolysis; as well as the plastic composition containing said mixed oxide.
    Type: Grant

  • Adhesive composition and method for bonding polyolefin surfaces with metal surfaces
    Patent number: 4062715
    Abstract: An adhesion assistant or binder composition for bonding polyolefin surfaces with metal surfaces comprising an aqueous dispersion of an ethylene/vinyl acetate copolymer from 0.5 to 5 parts by weight based on 100 parts of the copolymer of a cross-linking peroxide compound and from 1 to 10 parts by weight based on 100 parts of the copolymer of a low-molecular-weight 1,2-polybutadiene; as well as a process for producing composite bodies by heat and pressure utilizing the above adhesion assistant between polyolefin surfaces and metal surfaces.

  • Particulated rubber and plastics coverings and binders therefor
    Patent number: 4043962
    Abstract: A readily dryable adhesive binder for particulated rubber and/or plastics compositions comprising from 1% to 10% by weight of a water-solubleformaldehyde polycondensation resin, from 0.5% to 5% by weight of formaldehyde or a compound liberating formaldehyde, and from 85% to 98.5% by weight of a film-forming plastics dispersion; as well as a composition forming a resilient covering comprising from 40% to 75% by weight of particulated rubber and/or plastics and from 25% to 60% by weight of the above adhesive binder.
