摘要：
Provided is a copolymer rubber, comprising a copolymer having a star-shaped block structure (SIB-PA)n-X, wherein SIB is a block comprising styrene, butadiene, and isoprene as constituent monomers; PA is a block comprising butadiene or isoprene as a constituent monomer; X is the residue of at least one coupling agent; and n=2-4. Also provided is a process for preparing the copolymer rubber and use thereof.
