Abstract

PURPOSE: A composition, obtained by incorporating a specific propylene-ethylene block copolymer with a specific copolymer of ethylene with an α-olefin, haivng improved impact resistance at low and ordinary temperatures and transparency and good tensile elongation and moldability.
CONSTITUTION: (A) 100pts.wt. propylene-ethylene block copolymer having a melt flow index of 0.1W100g/10min, preferably 0.3W50g/10min, is incorporated with (B) 3W50pts.wt., preferably 5W30pts.wt., ethylene-α-olefin copolymer having a melt flow index of 0.01W100g/10min, preferably 0.1W30g/10min and a density of 0.910W 0.930g/cm3, preferably 0.915W0.925g/cm3. Improved transparency is obtained by using a copolymer prepared by copolymerizing propylene with 0.3W50wt% ethylene by the random copolymerization method in the first stage, and copolymerizing ethylene with the resultant copolymer in the second stage.
