PURPOSE:To obtain titled composition with both decreased rolling resistance and improved brake performance on wet road simultaneously achieved, by incorporating both benzophenone and aromatic amine in raw rubber. CONSTITUTION:The objective composition can be obtained by incorporating (A) 100pts.wt. of raw rubber (e.g. natural rubber, polyisoprene rubber) with (B) >=0.1pts.wt. of benzophenone of formula (R1 and R2 are each amino, alkylamino, etc.; m and n are each such integer that m+n falls between 1 and 10) and (C) >=0.5pts.wt. of aromatic diamine (e.g. N-phenyl-1-naphthylamine).
