Abstract

The object of the present invention is to provide a modified diene polymer capable of creating good reinforcing characteristics and filler dispersing effect independently of the kinds of the filler as well as a process for making the polymer and to provide a rubber composition having good fracture characteristics, wear resistance, and low exothermicity without the impairment of wet performance. The above-described object can be achieved by a process for making the polymer, said process comprising the steps of polymerizing or copolymerizing a conjugated diene monomer by using an organolithium compound as an initiator in a hydrocarbon solvent and thereafter allowing the active termination of the polymer to react with a compound having an alkylideneamino group represented by the following formula 1; ##STR1## wherein R, R', R', and R'' each represent a group having 1 to 18 carbon atoms selected from the group consisting of: an alkyl group, an allyl group, or an aryl group; and m and n are integers of from 1 to 20 and from 1 to 3, respectively.
