Abstract
PURPOSE: To provide the titled copolymer having excellent heat-sealability, transparency, and blocking resistance, suitable for film-forming, and composed of a block copolymer consisting of a propylene-based random terpolymer and a polymer composed mainly of ethylene.
CONSTITUTION: A block copolymer having an intrinsic viscosity of 0.8W1.5dl/g in decaline solutiin at 135°C, and composed of (A) 90W99wt% of a three-component random copolymer consisting of 80W98wt% of propylene, 5W1wt% of ethylene and 15W1wt% of hexene-1, and (B) 10W1wt% of an ethylene-based copolymer consisting of 80W100wt% of ethylene, 15W0wt% of propylene, and 10W 0wt% of hexene-1.
