POLYOLEFIN RESIN COMPOSITION

摘要

A polyolefin resin composition which comprises (A) a polyolefin (I) obtained from at least one monomer selected among alpha -olefins, cycloolefins, and styrene and derivatives thereof, (B) a polyolefin (II) which is obtained from the at least one monomer and is different in composition and properties from the polyolefin (I), and (C) a graft copolymer obtained by bonding the polyolefin (I) to the polyolefin (II) through a polyene, wherein the ratio of the relaxation rate of a long-relaxing ingredient (1/R>1<) in the composition as measured by solid ?1>H-NMR spectroscopy to the relaxation rate of a resin mixture consisting of the ingredient (A) and the ingredient (B) only (1/R1)0, i.e., [(1/R1)/(1/R1)0], is 1.01 or higher and the composition has an intrinsic viscosity [ eta ] (135 DEG C decalin) of 0.1 to 10 dl/g. This resin composition can be easily controlled with respect to factors which influence or develop morphology or material properties such as interfacial strength. Thus, a composite material comprising polyolefin resins can be designed according to properties required.
