Abstract
A thermoplastic elastomer composition containing a thermoplastic resin component including 10 to 95% by weight of a polypropylene having a syndiotactic structure and an elastomer component and having a value of .alpha., defined as follows, of 1 or less: EQU .alpha.=(.phi.d/.phi.m).times.(.eta.m/.eta.d) wherein the volume fraction of the thermoplastic resin component is .phi.m, the melt viscosity thereof at the mixing conditions is .eta.m and the volume fraction of the elastomer component is .phi.d, the melt viscosity thereof is .eta.d.
