| 摘要 |
The present invention relates to a rotomolded article, comprising at least one metallocene-catalyzed polyethylene resin comprising at least two metallocene-catalyzed polyethylene fractions A and B, wherein the polyethylene resin comprises: at least 25% to at most 55% by weight of polyethylene fraction A based on the total weight of the polyethylene resin, wherein fraction A has a melt index MI2 of at least 25.0 g/10 min as determined according to ISO 1133, condition D, at 190°C and under a load of 2.16 kg, and a density at least 0.005 g/cm 3 higher than the density of the polyethylene resin; and wherein the polyethylene resin has a density of at least 0.938 g/cm3 to at most 0.950 g/cm 3 as measured according to ASTM D-1505 at 23°C; a melt index MI2 of at least 1.0 g/10 min to at most 25.0 g/10 min as determined according to ISO 1133, condition D, at 190°C and under a load of 2.16 kg. The present invention also relates to a process for preparing said rotomolded article. |
