  • Patent number: 10533062
    Abstract: The present invention provides a modified conjugated diene-based polymer which includes a functional group derived from a substituted styrene-based compound and a functional group derived from an aminosilane-based compound, a method for preparing the same, and a rubber composition including the same. The modified conjugated diene-based polymer includes the functional group derived from an aminosilane-based compound of Formula 1 and a functional group derived from a substituted styrene-based compound of Formula 2 at both terminals of a main chain, and thus, shows a high modification ratio. When applying the polymer in a rubber composition, excellent affinity with a filler may be shown, and as a result, agglomeration of a filler in the rubber composition may be prevented, and the dispersibility of the filler may be increased, thereby improving the processability of the rubber composition.

  • Patent number: 10428161
    Abstract: Studies have been made for the purpose of achieving both the improvement in the storage stability of a solution-polymerized diene rubber that is modified with an alkoxysilane compound and the improvement in the physical properties of the diene rubber when blended with silica. Thus, a production method whereby it becomes possible to produce a modified solution-polymerized diene rubber having good storage stability and high reactivity with silica is developed, by introducing several tens percent of a three blanched or four blanched component that has been coupled with a tin compound into a modified solution-polymerized diene rubber, then coagulating the resultant alkoxysilane modified diene rubber with steam and then drying the coagulated product.
