Catalyst efficiency for supported metallocene catalyst |
摘要 |
The invention provides a process for making a metallocene catalyst supported on silica treated with MAO. The invention includes supporting the metallocene compound on a MAO-treated silica at a temperature of below 0 DEG C. The supported catalyst is activated with an aluminum alkyl. The catalyst may be prepolymerized in a tubular reactor prior to being introduced into the polymerization reaction zone.
