    摘要: Provided are a block copolymer and a thermoplastic elastomer composition each of which is excellent in both tensile strength and elastic recovery, and has good abrasion resistance. Specifically, provided are a hydrogenated block copolymer, which is obtained by hydrogenating a block copolymer having two or more polymer blocks (a) each containing a structural unit derived from an aromatic vinyl compound and one or more polymer blocks (b) each containing structural units derived from isoprene and 1,3-butadiene, in which the hydrogenated block copolymer has a crystallization peak temperature (Tc) defined as described below of -3 to 15°C, and a thermoplastic elastomer composition containing the hydrogenated block copolymer: (crystallization peak temperature (Tc)) a peak top temperature of an exothermic peak observed when the temperature of a sample is increased from 30°C to 150°C at a rate of temperature increase of 10°C/min and then the sample is cooled to -100°C at a rate of temperature decrease of 10°C/min, the peak top temperature being measured with differential scanning calorimeter (DSC), is defined as the crystallization peak temperature (Tc).

    摘要: A polymer consisting mainly of structural units represented by the general formula (1), wherein the total molar amount of terminal aldehyde groups and acetal groups is 0.6 mol% or smaller based on the total molar amount of the structural units represented by the general formula (1). -[-(-CHR1-)n-CX1R2-CX2R3-]- (1) (In the formula, n is an integer of 2 to 10; X1 and X2 each represents -H, -OH, or a functional group capable of being converted into -OH, provided that at least one of X1 and X2 is hydroxy or a functional group capable of being converted into hydroxy; and R1, R2, and R3 each represents -H or C1-5 alkyl, aryl, aralkyl, or heteroaryl and the two or more R1's may be different.)

    摘要: The present invention relates to a method for producing a hydrogenated block copolymer, including the steps of: (a) forming a block copolymer by allowing a living polymer having a specific structure to react with a tetra- or more functional silane coupling agent; (b) hydrogenating the block copolymer to form a hydrogenated block copolymer; (c) isolating the resultant hydrogenated block copolymer; and (d) deactivating a functional group in the silane coupling agent and/or an unreacted functional group present in a coupling agent residue in the block copolymer or the hydrogenated block copolymer prior to the step (c), in which the number of functional groups derived from the coupling agent in the hydrogenated block copolymer recovered in the step (c) is 1.5 or less per block copolymer molecule; a hydrogenated block copolymer obtained by the method; and a composition containing the hydrogenated block copolymer.
