ABSTRACT:
Tris(pentafluorophenyl)borane complexes having the general formula (C.sub.6 F.sub.5).sub.3 B.(YXH).sub.q wherein X is oxygen, or sulfur; q is 1 to 3; Y is a hydrogen atom, R.sup.1 --, (R.sup.2).sub.3 Si--, or (R.sup.3 ).sub.2 C.dbd.N--; R.sup.1 is a hydrocarbyl group containing 1 to 500 carbon atoms, and may contain a divalent oxygen and further may be a fluorine-containing hydrocarbyl group; R.sup.2 is independently a linear or branched alkyl group containing 1 to 25 carbon atoms, or a phenyl group, further R.sup.2 may contain a SiO-- group; and R.sup.3 is independently a hydrocarbyl group containing 1 to 25 carbon atoms, R.sup.3 may be a hydrogen atom provided both R.sup.3 groups selected are not hydrogen atoms; and to complexes containing the borane complexes with an organometallic compound, either as a neutral compound or as an acidic salt that are useful as catalysts for polymerization and copolymerization of olefins and to polymeric products prepared using these catalysts.
