Patent ID: 6946521

Claim:
A polyethylene resin comprising from 35 to 49 wt. % of a first polyethylene fraction of a high molecular weight and from 51 to 65 wt % of a second polyethylene fraction having a lower molecular weight than said first polyethylene fraction: (a) said first polyethylene fraction comprising a linear low density polyethylene having a density of no more than 0.930 g/cm 3 , and a high load melt index, HLMI, of less than 0.6 g/10 min; (b) said second polyethylene fraction comprising a high density polyethylene having a density of at least 0.969 g/cm 3 and a melt index, MI 2 , of greater than 10 g/10 min; and (c) said polyethylene resin having a density greater than 0.949-0.96 g/cm 3 , a high load melt index, HMLI, within the range of 1-100 g/10 min, a dynamic viscosity η 0.01 measured at 0.01 radian/second, which is greater than 200,000 Pa.s, and a ratio η 0.01 /η 1 which is greater than 8; wherein: (i) η 0.01 is the dynamic viscosity measured at 0.01 radian/second; and (ii) η 1 is the dynamic viscosity of the polyethylene resin measured at 1 radian/second.
