Abstract:
A thermoplastic elastomer composition comprising an ethylenei.&agr;-olefinic copolymeric rubber (A) whose intrinsic viscosity determined at 135Â° C. in decalin solvent is 3.5 to 6.8 dug, a mineral oil-based softener (B), an c-olefinic crystalline polymer (C) whose degree of crystallinity is 50% or higher and an a-olefinic amorphous polymer (D) whose melt viscosity at 190Â° C. is 50,000 cPs or less and whose degree of crystallinity is less than 50%, wherein at least a part of a mixture containing 20 to 63% by mass of said (A), 35 to 78% by mass of said (B), Ito 12% by mass of said (C) and 1 to 12% by mass of said (D), based on 100% by mass of the total of said (A), (B), (C) and (D), is crosslinked.
