METHOD FOR PRODUCING HYDROGENATED CONJUGATED DIENE POLYMER HYDROGENATED CONJUGATED DIENE POLYMER POLYMER COMPOSITION CROSS-LINKED POLYMER AND TIRE

摘要

A rubber material having balanced tensile strength, low hysteresis loss characteristic, wet grip property and abrasion resistance is provided. A hydrogenated conjugated diene polymer which is a hydrogenated product of a conjugated diene polymer having a structural unit derived from butadiene is obtained by the steps of: obtaining the conjugated diene polymer having a functional group interacting with silica in a side chain portion; Of the structural unit derived from butadiene so that the hydrogenation rate of the structural unit derived from the butadiene is 80 to 99%.
