PURPOSE:To provide a polyethylene compsn. which is excellent in molding characteristics, such as draw-down resistance and moldability into a uniform wall thickness. and in impact strength and is suitable esp. for a large-sized blow molding. CONSTITUTION:A polyethylene compsn. has a high-load melt index of 0.5-10g/10 min and contains 80-99wt.% polymer component consisting of an ethylene homopolymer and/or a copolymer of ethylene with another alpha-olefin and 1-20wt.% polymer component having a degree of crystallization lower than 30% and consisting of a copolymer of ethylene with a 3C or higher alpha-olefin, the sum of both the polymers being 100wt.%. |
