摘要：
The present invention relates to a method for producing a hydrogenated block copolymer, comprises the steps of: (a) forming a block copolymer by allowing a living polymer having a specific structure to react with a bis-silane coupling agent having a specific structure; (b) hydrogenating the block copolymer to form a hydrogenated block copolymer; and (c) isolating the resultant hydrogenated block copolymer, in which the number of functional groups derived from the coupling agent in the hydrogenated block copolymer isolated 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.
