Abstract: Biscyclopentadienyl, Group 4 transition metal complexes are formed by contacting a biscyclopentadienyl Group 4 metal halide, hydrocarbyl, hydrocarbyloxy or amide complex with a conjugated diene. Uniquely, the ansa-rac diastereomer is selectively isolated and may be reconverted to the halide form if desired. When combined with standard activating cocatalysts or activated with an activating technique, the complexes form catalysts for polymerizing olefins, diolefins and/or acetylenically unsaturated monomers.
Abstract translation: 双环戊二烯基，第4族过渡金属络合物通过使双环戊二烯基第4族金属卤化物，烃基，烃氧基或酰胺络合物与共轭二烯接触而形成。 独特地，ansa-rac非对映异构体被选择性地分离并且如果需要可以被重新转化为卤化物形式。 当与标准活化助催化剂结合或用活化技术活化时，络合物形成用于聚合烯烃，二烯烃和/或炔属不饱和单体的催化剂。

Abstract: Boratabenzene cocatalysts, especially novel pentafluorophenyl boratabenzenes, are useful cocatalysts or activators with metallocenes. They are less expensive than prior art activators, are soluble and offer more irreversible reactions. Compositions comprise at least one metallocene catalyst and at least one dihydroboratabenzene or anion thereof. Processes include polymerizations with metallocenes in the presence of boratabenzene cocatalyst and activation process including bulk electrolysis techniques.
