    摘要: A carbon-containing rubber composition containing a rubber composition containing carbon black, obtained by coagulating, dehydrating, and drying a rubber latex mixture containing a latex of at least one starting rubber A having an average glass transition temperature TgA of -120.degree. C. to -15.degree. C., carbon black, and part of a softening agent, mixed in an internal mixer with a starting rubber B and part of the softening agent, with a ratio F.sub.A /F.sub.B of the concentration F.sub.A of carbon black in the copolymer in the rubber latex mixture with the concentration F.sub.B of carbon black in the copolymer after kneading by the hermetic mixture being 1.2 to 3.0 and a rubber composition containing carbon black comprising a starting rubber A' comprising a polymer having functional groups represented by formula (I)--C.dbd.N'-- (I)bonded with a polymer chain directly or through another atomic group or a terminal modified diene-based polymer first brought into contact with carbon black, then blended with a starting rubber B' comprising a diene based stock rubber.

    摘要: A process for producing a rubber composition comprising (i) a total amount of 100 parts by weight of starting rubbers (A) and (B), including 30 to 90 parts by weight of the starting rubber (A) having a glass transition temperature (Tg) of -40.degree. to 10.degree. C. and 10 to 40 parts by weight of the starting rubber (B) which is viscoelastically incompatible with the starting rubber (A) and has a Tg of at least 20.degree. C. lower than the Tg of the starting rubber (A) and (ii) 60 to 100 parts by weight of a reinforcing agent, wherein the starting rubber (A) and at least 80% by weight of the total weight of the reinforcing agent are mixed in a hermetic type mixer at 130.degree. C. to 200.degree. C. for at least 10 seconds, then the starting rubber (B) and the remaining reinforcing agent are added and mixed.
