    摘要: A butadiene-based rubber composition is disclosed, which contains not less than 20% by weight of a butadiene-based homopolymer or copolymer having a glass transition temperature (Tg) of not less than -105.degree. C., but less than -70.degree. C. and a Mooney viscosity (ML.sub.1+4, 100.degree. C.) of 10 to 150. The butadiene-based homopolymer or copolymer is obtained by polymerizing butadiene or random-copolymerizing butadiene with at least one kind of a monomer selected from the group consisting of another conjugated diene and an aromatic vinyl compound, and then reacting polymerization-active terminals thereof with an isocyanate compound and/or an isothiocyanate compound. The butadiene-based rubber composition has excellent resilience, fracture strength, and wear resistance as a vulcanizate as well as excellent processability as an unvulcanized rubber, and can be used as tire applications such as tire treads, undertreads, sidewalls, bead portions, etc. as well as vibration insulating rubber, hoses, belts and other industrial articles.

    摘要: A rubber composition for use in tire is disclosed which contains at least 30% by weight, relative to the entire rubber component, of a conjugated diene-monovinyl aromatic hydrocarbon copolymer which uses an organic lithium compound as an initiator. A percentage of vinyl bonds in conjugated diene units in the copolymer molecules is from 50 to 95% and the content of the monovinyl aromatic hydrocarbon units is from 10 to 50% by weight. As physical properties of the vulcanized rubber of the rubber composition, aromatic hydrocarbon copolymer, 200% tensile modulus is from 5 to 50 kgf/cm.sup.2 and a temperture integrated value of a loss tangent, ##EQU1## is from 16 to 56. The tread rubber composition is suitable for a tread of high performance tires, and is excellent in fracture strength, thermal resistance, wear resistance, and road gripping property.

    摘要: A thermoplastic resin composition obtainable by blending 100 parts by weight of a mixture consisting of(A) 75 to 40% by weight of a propylene polymer,(B) 20 to 40% by weight of an ethylene-alpha-olefin copolymer, and(C) 5 to 30% by weight of a graft copolymer obtained by copolymerizing an aromatic vinyl compound and a polar vinyl compound in the presence of an ethylene-alpha-olefin copolymerwith(D) 0.1 to 5 parts by weight of an unsaturated dicarboxylic acid, an anhydride thereof or a mixture of the two, and(E) 0.01 to 0.3 part by weight of an organic radical-generating agent,and then subjecting the resulting blend to thermal treatment. Said composition has not only a high bending modulus inherently possessed by polypropylene resins but also remarkably improved coating property. Accordingly, the composition is useful as interior and exterior trim parts of automobiles and exterior trim parts of motorcycles.
