Patent ID: 6875827

Claim:
A hydrogenated polymer which is a hydrogenation product of a conjugated diene polymer having an average vinyl bond content of 20% by weight or more and less than 50% by weight and a weight average molecular weight of 60,000 to 600,000 to a degree such that 85% or more of residual double bonds in the conjugated diene units are hydrogenated, and which has a molecular weight and a number of carbon atoms of terminal methyl groups as measured by GPC/FTIR analysis satisfying relationship (1) Va−Vb ≧0.03 Vc (1) wherein Va, Vb and Vc represent the number of terminal methyl group carbon atoms per 1000 carbon atoms contained in a polymer whose molecular weight is twice the peak top molecular weight, half the peak top molecular weight, and the peak top molecular weight, respectively.
