发明名称 Ethylene polymer
摘要 An ethylene polymer excellent in molding processability represented by uniform extensibility, drawdown resistance, swell and extrudability, and mechanical properties represented by rigidity, impact resistance and ESCR, is provided. Particularly, an ethylene polymer remarkably excellent in balance between rigidity and ESCR as compared with a conventionally known ethylene polymer is provided. An ethylene polymer, which is an ethylene homopolymer or a copolymer of ethylene with an alpha-olefin having a carbon number of from 3 to 20, and which satisfies the following conditions (1) to (4): (1) the melt index (HLMI) under a load of 21.6 kg at 190° C. is from 0.1 to 1000 g/10 min, (2) the density (d) is from 0.935 to 0.985 g/cm<3>, (3) the relation between HLMI and (d) satisfies the following formula (i): d>=0.00900xLog(HLMI)+0.951 (i) (4) the relation between ESCR and the flexural modulus (M) satisfies the following formula (ii): M>=-7310xLog(ESCR)+32300 (ii)
