    • The present invention relates to polybutadiene grafted isoprene rubber, a manufacturing method thereof, polybutadiene grafted isoprene rubber manufactured thereby and vulcanizate and a mixed compound manufactured from the polybutadiene grafted isoprene rubber. The polybutadiene grafted isoprene rubber comprises: butadiene structural units in an amount ranging from about 0.5% to about 8% by weight; and isoprene structural units in an amount ranging from about 92% to about 99.5% by weight, calculated on the basis of the total weight of the polybutadiene grafted isoprene rubber, wherein the number-average molecular weight of the polybutadiene grafted isoprene rubber ranges from about 2×105 to about 5×105; and the molecular weight distribution of the polybutadiene grafted isoprene rubber ranges from about 3 to about 4; the branching factor of the polybutadiene grafted isoprene rubber ranges from about 0.5 to about 0.98; and the polybutadiene grafted isoprene rubber in cis-1,4-structure is in an amount ranging from about 95% to about 99% by weight calculated on the basis of the total weight of the polybutadiene grafted isoprene rubber. The polybutadiene grafted isoprene rubber provided by the present invention has excellent mechanical properties and desirable processability. Also, the manufacturing method disclosed in the present invention is simple and easy to control, and can control the composition and molecular weight of manufactured polymers efficiently and correctly. Therefore, the present invention is a very valuable method in an industrial application field.
