| abstract |
In the present invention, it is possible to improve the dispersibility of an inorganic filler when applied to a rubber composition including a functional group derived from a modifier of the following formula (1) and to improve the viscoelasticity, tensile property and workability of the rubber composition by well- Modified butadiene polymer and a denaturant useful in the production thereof. [Chemical Formula 1] (Wherein, A, R 1 to R 5 , m and n are as defined in the specification) |
