| Abstract: | The structure and properties of rotational molding polyethylene resins respectively produced by metallocene catalyst and titanium catalyst were analyzed and studied by GPC,13 C NMR,SSA,drop hammer impact and ESCR experiments.Comparing with PE-2 rotational molding resin produced by titanium catalyst,the experiments results showed that mPE-1 rotational molding resin produced by metallocene catalyst possessing the following characteristics such as narrower molecular weight distribution,less branching point of molecular chain,easier formation of thicker lamellar crystal,more uniform thickness distribution of lamellar crystal,better mechanical properties,which resulted in excellent drop hammer impact and ESCR performances of the mPE-1. |
