  • 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.

  • Polyisoprene, preparation method thereof, polyisoprene rubber compounds and vulcanizate therefrom
    Patent number: 8940838
    Abstract: The method for preparation of polyisoprene includes conducting polymerization reaction of isoprene in a first organic solvent under the presence of rare earth catalyst I and rare earth catalyst II, to obtain polyisoprene with bimodal molecular weight distribution, wherein the polymerization reaction conditions are controlled to ensure the peak molecular weight of the high molecular weight component fraction in the polyisoprene is 1×106-2×106 and the peak molecular weight of the low molecular weight component fraction is 2×105-4×105, and the weight ratio of content of the high molecular weight component fraction to the low molecular weight component fraction is 1-25:1. The molecular weight distribution of the polyisoprene obtained with the method provided is bimodal distribution; therefore, the polyisoprene not only has the mechanical properties of polyisoprene with high molecular weight, but also has the processability of polyisoprene with low molecular weight.
