<p>1,194,884. Rubber laminates. SUMITOMO CHEMICAL CO. Ltd. 19 May, 1967 [26 May, 1966], No. 48111/69. Divided out of 1,194,883. Heading B5N. [Also in Division C3] Laminates are prepared from compounded rubbers and from a compounded rubber and a metal or fabric of natural and synthetic fibre using as adhesive a solution of a polymeric material which is (1) a graft copolymer produced by polymerizing an unsaturated compound with a halogenated ethylene/C 3-8α-olefin/non- conjugated diene terpolymer containing 13-50 weight per cent of chlorine and/or bromine; (2) a blend of a halogenated terpolymer as defined in (1) with a graft copolymer produced by polymerizing an unsaturated compound with a terpolymer as defined in (1); or (3) a blend of a graft copolymer as defined in (1) with a halogenated terpolymer as defined in (1), optionally together with fillers and vulcanizing agents. Specified unsaturated compounds are acrylic and methacrylic acids, esters and amides, acrylonitrile, 2-vinyl pyridine, 4-vinyl pyridine and 2 - methoxy - 5 - vinyl pyridine. In Examples (I) an adhesive comprising an ethylene/ propylene/dicyclopentadiene terpolymer/methacrylic acid graft copolymer, chlorinated terpolymer, carbon black, benzotrichloride, stannous chloride, carbon tetrachloride and toluene is used to bond compounded EPDM rubbers to compounded butyl, natural, butadiene/styrene and polychloroprene rubbers; and (2) a solution of a chlorinated/brominated terpolymer/4-vinyl pyridine/2 - methoxy - 5 - vinyl pyridine graft copolymer is used to bond compounded EPDM rubbers to compounded polychloroprene rubber, nylon woven fabric and rayon woven fabric.</p> |
