    • A rubber composition for tire tread is disclosed, which is prepared by compounding specific amounts of carbon black, white carbon and sulfur in a mixed rubber component of styrene-butadiene copolymer rubber obtained by emulsion polymerization wherein the amount of bound styrene is 30 to 40 wt %, wherein the amount of isolated styrene (S1) based on total bound styrene amount is 58 % or more, and wherein sum of isolated styrene (S1) and styrene chain composed of two styrene units (S2) based on total bound styrene amount is 87.5 % or more, preferably mixed with a styrene-butadiene copolymer rubber obtained by solution polymerization wherein the amount of bound styrene is 10 to 20 wt %, wherein the amount of isolated styrene (S1) based on total bound styrene amount is 80 % or more, and wherein a sum of the bound styrene and bound vinyl amount in butadiene moiety is 70 wt % or less. When used as tire tread, this composition reduces temperature dependence of hardness of the tire tread surface, prevents sticking and adhesion of rubber tailings, and markedly improves driving stability and gripping properties in driving in winter.

    • A method of producing compounds in which the rubber phase contains a polyolefin and a halobutyl rubber, which is partially crosslinked, to which composition is then added additional polyolefin and a vulcanizable olefinic rubber, which is then further crosslinked using organic peroxides, and then blended with a styrenic rubber. The TPE compounds incorporate (A) polypropylene 10-90 weight parts (wt. pts.), (B) halobutyl rubber 90-10 wt. pts. (where (A) + (B) = 100), (C) an olefinic rubber 10-120 wt. pts., (D) mineral oil softener 5-120 wt. pts., which are then treated thermally inthe presence of (E) MOx and/or MCl, to which composition of 100 weight parts is added (F) polyolefin 100-600 wt. pts., and (G) a vulcanizable olefinic rubber 50-500 wt. pts. The resulting blend is then thermally treated with (H) organic peroxide(s), to which blend of 100 wt. pts. is then added and uniformly dispersed (I) 5-150 wt. pts. of styrenic rubber. The method produces thermoplastic elastomer compositions which can be molded into large parts with smooth surfaces that accept paint well, have a good balance of flexibility and strength.
