Abstract: Disclosed is a thermoplastic elastomer composition obtained by dynamically heat-treating a mixture containing a thermoplastic resin (A) having a melting point of not less than 200˚C and an elastomer (B) having a constitutional unit derived from an ester group-containing monomer in the presence of a polymer (C-1) which is composed only of a (meth)acrylate unit (c-1) and has a weight average molecular weight Mw of 1,000-30,000 and a molecular weight distribution Mw/Mn of 1.0-4.0 and/or a polymer (C-2) which is composed of 5-35 mass% of a (meth)acrylate unit (c-1) and 65-95 mass% of an aromatic vinyl monomer unit (c-2) and has a weight average molecular weight Mw of 1,000-30,000 and a molecular weight distribution Mw/Mn of 1.0-4.0, as a crosslinking agent (C). Such a thermoplastic elastomer composition has a good sea-island structure as a whole and is excellent in cold resistance. Consequently, the thermoplastic elastomer composition is useful as an alternative to acrylic rubbers.
