Abstract:
1. A polyolefin-based resin composition, comprising (A) a polyolefin I produced from at least one monomer selected from the group consisting of a C (B) a polyolefin II produced from at least one monomer selected from the group consisting of a C (C) a graft copolymer produced by bonding said polyolefins I and II, present in said polyolefin-based resin composition, to each other through a polyene, which has a xylene-insoluble content at 140° C. of 0 to 2.5% by weight, and a polyene-derived residual carbon-to-carbon double bond content of 0 to 0.15 mol %, wherein said component (A) and said component (B) are present at a weight ratio of 1:99 to 99:1, and further said component (C) is present in an amount of 0.01 to 30% by weight based on the total weight of said components (A) and (B), and wherein 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., and wherein the polyene is a compound selected from the group consisting of α, ω-polyenes represented by the following formula II; wherein Q is a single bond or C styrene-type polyenes represented by the following formula III: wherein R cyclic polyenes represented by the following formula IV: wherein R cyclic polyenes represented by the following formula V: wherein R cyclic polyenes represented by the following formula VI: wherein subscript b is 0, 1 or 2; cyclic polyenes represented by the following formula VII: wherein c is an integer of 1 or 2; and d is an integer of 0 to 11; cyclic polyenes represented by the following formula VIII: wherein e is an integer of 0 to 6; styrene/α-olefin-type polyenes represented by the following formula IX: wherein R
