| 主权项 | 1. A polybutadiene grafted isoprene rubber, comprising a) butadiene structural units in an amount ranging from about 0.5% to about 8% by weight; and b) 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; 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. | ||
