    • The object is to provide a conjugated diene polymer which shows excellent balance among wet skid property, low hysteresis loss property, abrasion resistance and fatigue strength when vulcanized into a vulcanized rubber regardless of the types or combinations of a filler to be blended and is useful as a material for a tire tread, and a process for production of the polymer. Thus, disclosed is a diene copolymer produced by reacting a conjugated diene polymer with a low molecular weight compound. The low molecular weight compound has in it molecule at least one secondary amino group having three organic substituted silyl groups substituted for hydrogen atoms therein, at least one organic group having an N atom not adjacent to an N atom in the secondary amino group, and at least one alkoxysilyl group. Alternatively, the low molecular weight compound has at least one heterocyclic ring having a secondary amino group that has three organic substituted silyl groups substituted for hydrogen atoms therein, and at least one alkoxysilyl group. Further disclosed are a hydrolysis product of the diene polymer, a polymer composition comprising the diene polymer and a hydrolysis product thereof, a composition comprising the diene polymer and a conjugated diene polymer coupled with a polyfunctional modifier, and a process for production of any one of the polymer, hydrolysis product and compositions.
