Abstract: An olefin-based thermoplastic elastomer comprises a propylene-based resin (A) and an olefin-based copolymer rubber (B), and has a ratio (N1/SS) of first normal stress difference (N1) to shear stress (SS) of 0.6:1 to 1.4:1 said first normal stress difference (N1) and shear stress (SS) being determined by subjecting said elastomer to step shear test at a temperature of 200° C. and a shear rate of 25.1 sec−1. Such olefin-based thermoplastic elastomer shows excellent moldability, transferability of embossed patterns and mechanical strength.

Abstract: Disclosed is a olefin resin composition comprising a propylene resin (PP) and an ethylene resin (PE) at a PP:PE mixing ratio of 97 to 60:3 to 40 by weight, the propylene resin and the ethylene resin having such dynamic melt viscoelasticity that the PE to PP viscosity ratio, i.e., .eta.r=.eta.PE/.eta.PP, is more than or equal to 0.1 and less than 1 at 1 rad/sec and more than or equal to 0.70 at 100 rad/sec and that the difference of modulus of melt elasticity between PP and PE, i.e., .DELTA.G'=GPP-GPE, is 10000 Pa or more; an olefin sheet comprising the olefin resin composition; and an olefin resin laminated sheet having a surface layer and an intermediate layer in which the intermediate layer comprises the olefin resin composition.
