Abstract
A process for making a diene polymer rubber which comprises reacting an active diene polymer rubber having alkali metal and/or alkaline earth metal terminals, which is obtained by polymerizing a conjugated diene monomer alone or together with an aromatic vinyl monomer in a hydrocarbon solvent, using an alkali metal and/or alkaline earth metal initiator, with PA0 (1) a tin compound expressed by the general formula R.sub.a S.sub.n X.sub.b (in which R stands for an alkyl, alkenyl, cycloalkenyl or aromatic hydrocarbon group; X is a halogen atom; a is an integer of 0-2, and b is an integer of 2-4), and PA0 (2) at least one organic compound selected from the group consisting of aminoaldehydes, aminoketones, aminothioaldehydes, aminothioketones and the organic compounds having in their molecules ##STR1## (in which A stands for an oxygen or sulfur atom).
