Abstract:
A hydrogenated polymer obtained by hydrogenating a conjugated diene polymer having an average vinyl bond content of 20% by weight or nore and less than 40% by weight to a degree such that 85% or more of double bond residues in the conjugated diene unit portion are hydrogenated, wherein(1) the crystallizing peak temperature and the hydrogenated vinyl bond content satisfy the formula: âˆ’2.8V+1002.8V+130 wherein T is the crystallizing peak temperature (Â° C.) measured by DSC; and V is the hydrogenated vinyl bond content (%),(2) the weight average molecular weight is 60,000 to 600,000, and (3) the molecular weight distribution is 1.55 to 5.0.
