Document Type and Number:
WIPO Patent Application WO1993021238
Kind Code:
A3
Abstract:
Tris(pentafluorophenyl)borane complexes having the general formula (C6F5)3B.(YXH)q wherein X is oxygen, or sulfur; q is i to 3; Y is a hydrogen atom, R1-, (R2)3Si-, or (R3)2C=N-; R1 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; R2 is independently a linear or branched alkyl group containing 1 to 25 carbon atoms, or a phenyl group, further R2 may contain a SiO- group; and R3 is independently a hydrocarbyl group containing 1 to 25 carbon atoms, R3 may be a hydrogen atom provided both R3 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.
