Abstract
PURPOSE: To provide the titled resin composition having excellent impact characteristics and being suitable for injection molding, by mixing a relatively high molecular weight ethylene-α-olefin copolymer with a relatively low molecuar weight ethylene-α-olefin copolymer in a specific mixing ratio.
CONSTITUTION: 10W70wt% ethylene-α-olefin copolymer (A) having a density of 0.905W0.94g/cm3, an intrinsic viscosity of 1.2W4dl/g and a degree of short chain branching per 1,000 carbons of 5W25 and 90W30wt% ethylene-α-olefin copolymer (B) having a density of 0.925W0.95g/cm3, an intrinsic viscosity of 0.3W1.2dl/g and a degree of short chain branching per 1,000 carbons of 8W20 are mixed in a ratio of the degree of short chain branching of component A to that of component B of 0.6 or more to provide the titled resin composition having a density of 0.93W0.95g/cm3, a melt index of 2W30g/10min and a melt flow ratio of 40W 80.
