ABSTRACT:
The present invention relates to 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 the residual double bonds in the conjugated diene units are hydrogenated, and which has a molecular weight and a number of terminal methyl group carbons as measured by GPC/FTIR analysis satisfying relationship (1):in-line-formulae description="In-line Formulae" end="lead"?Va−Vb≧0.03Vc  (1)in-line-formulae description="In-line Formulae" end="tail"?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.
