摘要:
PROBLEM TO BE SOLVED: To provide a conjugated diene copolymer giving a rubber composition which is excellent in the interaction between a rubber component and an inorganic filler such as silica, thus capable of further improving the dispersibility of the filler, and excellent in fracture resistance and abrasion resistance. SOLUTION: The conjugated diene copolymer is composed of (a) conjugated diene compound-derived constitutive units and (b) a constitutive unit represented by general formula (1) [wherein, X is Si, Sn or Ge; R 1 is a hydrocarbon group or -SiR 3 (wherein, R is a hydrocarbon group, and three R groups may be the same as or different from each other); R 2 is a hydrocarbon group; n is an integer of 1-3; when there are two or more OR 1 groups, they may be the same as or different from each other; when there are two or more R 2 groups, they may be the same as or different from each other].
