PROCESS FOR PREPARING POLYOLEFINS AND USE OF ANTIFOULING AGENTS THEREIN |
摘要 |
A process of preparing a polyolefin in a loop reactor in the presence of antifouling agent can include feeding into the loop reactor diluent, monomers, optionally hydrogen, and optionally one or more co-monomers to produce a liquid phase. Antifouling agent and catalyst can be introduced into the loop reactor. The process can include polymerizing the monomers and optional co-monomers to form the polyolefin. The process can be characterized in that a time difference between introduction of the antifouling agent and introduction of the catalyst is at most 3 hours. The process can be characterized in that the catalyst is introduced into a liquid phase when a concentration of the antifouling agent ranges from 0 ppm to less than 0.3 ppm. |
