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.
