Abstract:
A process to produce a multimodal polyolefin in a single reactor comprising:a) continuously combining a catalyst component slurry with a catalyst component solution to form a catalyst composition; b) combining the catalyst composition with one or more olefin(s) in a polymerization reactor to form a multimodal polyolefin; c) measuring a sample of the multimodal polyolefin to obtain an initial multimodal polyolefin property; d) changing the amount of catalyst component solution combined in (a) relative to the amount of catalyst component slurry to obtain a second product property; and e) isolating the multimodal polyolefin product; wherein the catalyst component slurry comprises one or more catalyst compounds, one or more activators and one or more support materials; and the catalyst component solution comprises one or more catalyst compounds, wherein the catalyst compounds may be the same or different.
