Abstract
A thermoplastic elastomer composition having excellent heat aging characteristics, weather resistance, low-temperature physical properties, oil resistance and flexibility, and moldings using the same, such as hoses, are disclosed. The thermoplastic elastomer composition is obtained by dynamically heat treating a mixture containing (A) an olefin resin, (B) an unsaturated group-containing acrylic rubber, and (D) an inorganic filler in the presence of (E) a crosslinking agent, the component (B) comprising (B1) from 55 to 94.99% by weight of a structural unit derived from an acrylic acid alkyl ester monomer and/or an acrylic acid alkoxyalkyl ester monomer, (B2) from 0.01 to 20% by weight of a structural unit derived from a monomer having a carbon-carbon double bond in a side chain thereof, (B3) from 5 to 30% by weight of a structural unit derived from an unsaturated acrylonitrile monomer, and (B4) from 0 to 30% by weight of a structural unit derived from a monomer copolymerizable therewith, provided that the sum of (B1), (B2), (B3) and (B4) is 100% by weight.
