<p>A process for producing a modified polymer by modifying a polymer having an active site, which comprises incorporating a residue of a hydrocarbyl compound into the polymer at the active site; and a rubber composition containing the modified polymer obtained by the process, preferably comprising 100 parts by weight of (A) a rubber ingredient comprising at least 30 wt.% the modified polymer and 10 to 100 parts by weight of (B) silica and/or carbon black. The modified polymer produced by the process gives a silica- and/or carbon black-containing rubber composition which has enhanced interaction between the rubber ingredient and the silica and carbon black, is improved in failure characteristics and wearing resistance, and has reduced heat build-up and satisfactory workability.</p> |
