METALLOCENE-CATALYZED POLYETHYLENE |
摘要 |
A metallocene-catalyzed polyethylene resin having a multimodal molecular weight and composition distribution, comprising from 45% by weight to 75% by weight of a low density fraction, said fraction having a density below or equal to 0.918 g/cm3 as measured following the method of standard test ISO 1 183 at a temperature of 23 °C, wherein the density of the polyethylene resin is from 0.920 to 0.945 g/cm3, wherein the Mw/Mn of the polyethylene is of from 2.8 to 6, wherein the melt index MI2 of the polyethylene resin of from 0.1 to 5 g/10min measured following the method of standard test ISO 1 133 Condition D at a temperature of 190 °C and under a load of 2.16 kg; and wherein the composition distribution breadth index (CDBI) of the polyethylene resin is below 70%, as analyzed by quench TREF (temperature rising elution fractionation) analysis. |
