Group-15 cationic compounds for olefin polymerization catalysts |
| abstract |
This description addresses fluorinated amine compounds meeting the general formula R′ i ArF-ER 2 , where ArF is a fluoroaryl group, E is nitrogen or phosphorous, each R is independently a C 1 -C 20 hydrocarbyl group, or the two Rs may connect to form an unsubstituted or substituted C 2 -C 20 cycloaliphatic group, R′ is a C 1 -C 20 hydrocarbyl or halogenated hydrocarbyl, and i is 0, 1 or 2. These compounds may be protonated with strong Bronsted acids to form protonated amine compounds that are useful for the preparation of organometallic catalyst-cocatalyst compounds comprising noncoordinating or weakly coordinating anions. The resulting organometallic catalyst-cocatalyst complexes can be effectively used as olefin polymerization catalysts. High number-average molecular weight polymers at high rates of productivity were observed from the use of metallocene catalyst complexes prepared with [N-pentafluorophenyl pyrrolidinium][tetrakis(pentafluorophenyl)borate] of [N-pentafluorophenyl pyrrolidinium][chloride]. |
