Abstract: Provided is a method for producing a butene polymer, comprising: a polymerization step of performing polymerization reaction by contacting a raw material component comprising 20% by mass or more of isobutene with a Lewis acid catalyst; and a distillation step of subjecting a solution to be treated containing a reaction product of the polymerization reaction and a butene oligomer added to the reaction product to distillation treatment to obtain the butene polymer, wherein an amount of the butene oligomer added is 25 parts by mass or larger with respect to 100 parts by mass of the reaction product.

Abstract: A thermoplastic elastomer composition having at least one elastomer component selected from the group consisting of elastomeric polymers (A) each of which has a side chain (a) containing a hydrogen-bond cross-linkable moiety having a carbonyl-containing group and/or a nitrogen-containing heterocycle and has a glass-transition point of 25° C. or below, and elastomeric polymers (B) each of which contains a hydrogen-bond cross-linkable moiety and a covalent-bond cross-linking moiety in a side chain and has a glass-transition point of 25° C. or below; and a clay, wherein an amount of the clay contained is 20 parts by mass or less relative to 100 parts by mass of the elastomer component.
