  • Functional diene polymer, preparation method thereof, and rubber composition comprising the same
    Patent number: 9296840
    Abstract: The present invention provides a functional diene polymer, a preparation method thereof and a rubber composition comprising the functional diene polymer. The functional diene polymer comprises at least one type of conjugated diene structural units and silane coupler functional units represented by formula (I) in its molecular chain, and the number-average molecular weight of the functional diene polymer is 50,000˜1,000,000; R1-R4 are C1-C20 linear or branched alkyl or heteroatom-containing C1-C20 linear or branched alkyl, and the heteroatom is selected from one or more of halogen, oxygen, sulfur, silicon, and phosphorus. Not only the relationship between the wet slip resistance and the rolling resistance of the functional diene polymer is effectively improved, but also the offensive odor produced in the rubber mixing process owing to the addition of the silane coupler is reduced.

  • Copolymer rubber having a star-shaped block structure, the preparation process and use thereof
    Patent number: 9133293
    Abstract: 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.
