Abstract

The present invention provides a polyolefin-based resin composition, comprising (A) a polyolefin I produced from at least one monomer selected from the group consisting of α-olefins, cyclic olefins and styrenes; (B) a polyolefin II produced from said at least one monomer, which differs in composition or properties from said polyolefin I; and (C) a graft copolymer produced by bonding said polyolefins I and II to each other through a polyene, wherein (a) a ratio [(1/R)/(1/R)] of a relaxation velocity (1/R) of a long-term relaxation component measured by a solidH-NMR method about the composition to a relaxation velocity (1/R)of a long-term relaxation component measured by a solidH-NMR method about a resin mixture of only the components (A) and (B) is 1.01 or higher; and (b) an intrinsic viscosity [η] of the composition is in the range of 0.1 to 10 deciliter/g as measured in decalin at 135° C. The resin composition is readily controlled in property-determining factors such as morphology and interfacial strength, and is capable of providing a composite material composed of polyolefin-based resins according to properties as required.
