Ethylene based polymer resin obtained by catalytic copolymerization of ethylene with a alpha-olefin useful in many applications as a multi-purpose resin of outstanding processing and mechanical properties

摘要

An ethylene based polymer resin obtained by copolymerization of ethylene with a 5-20C alpha-olefin, and of melt index (MFR), determined at 190 degrees C under a load of 21.18 N in accordance with Japanese industrial standard JIS K7210-1995, of not less than 0.01 g/10 minutes and less than 1 g/10 minutes, where the melt index and the melt strain (sic) (MT) at 190 degrees C (unit: cN) of the resin comply with two given inequalities is new. An ethylene based polymer resin obtained by copolymerization of ethylene with a 5-20C alpha-olefin, and of melt index (MFR), determined at 190 degrees C under a load of 21.18 N in accordance with Japanese industrial standard JIS K7210-1995, of not less than 0.01 g/10 minutes and less than 1 g/10 minutes, where the melt index and the melt strain (sic) (MT) at 190 degrees C (unit: cN) of the resin comply with the inequalities: (1) and (2): 2 x MFR-0.59 less than MT less than 3.6 x MFR-0.66 (1) 1.02 x MFR -0.094 less than (eta) less than 1.50 x MFR0.156 (2)
