Abstract
A rubber composition comprising (i) 100 parts by weight of a rubber and (ii) 10 to 180 parts by weight of a composite composed of an oxidative condensate obtained by oxidative condensation of a π-electron aromatic compound and carbon black and a pneumatic tire using the same as a tire tread.
Claims8
A pneumatic tire using, for a tire tread, a rubber composition comprising (i) 100 parts by weight of a rubber and (ii) 10 to 180 parts by weight of a composite composed of an oxidative condensate obtained by oxidative condensation of a π-electron aromatic compound selected from the group consisting of aniline, 2-methyl-aniline, naphthylamine, phenylenediamine, naphthylenediamine, triaminobenzene, triaminonaphthalene, pyrrole, indole, carbazole, thiophene, selenophene, imidazole, furan and their derivatives and carbon black.
A pneumatic tire using, for a tire tread, a rubber composition comprising (i) 100 parts by weight of a rubber and (ii) 10 to 180 parts by weight of a π-conjugated polymer compound selected from the group consisting of polyaniline, poly(2-methyl-aniline), polypyrrole, polythiophene, and carbon black.
