CATALYST FOR BIOMODAL MOLECULAR WEIGHT DISTRIBUTION ETHYLENE POLYMERS AND COPOLYMERS |
| 摘要 |
The interaction of silica, previously calcined at 600 DEG C., with dibutylmagnesium (DBM), 1-butanol and titanium tetrachloride and a solution of methylalumoxane (MAO) and (BuCp)2ZrCl2 provides a catalyst that, in the absence of a trialkylaluminum (AlR3) cocatalyst, produces polyethylene with a bimodal MWD. |
