  • Transition And Organic Metals Composition Catalysts For Addition Polymerization (AREA)

Abstract

A catalyst composition is disclosed for catalyzing the polymerization and copolymerization reactions of ethylene monomers, with or without another olefin monomer. The catalyst composition comprises a metallocene compound represented by the formula of (C5RnH5-n)(L)MXY or the formula of (C5RnH5-n)(L)MX+A-; wherein: (a) C5RnH5-n is a substituted or unsubstituted cyclopentadienyl group; (b) L is tetrapyrazolyl borate, hydrotrispyrazolyl borate, dihydrotrispyrazolyl borate or hydrotris-3,5-dimethyl; (c) M is group III B, group IVB, or group VB transitional metal; (d) X is a C1 to C4 alkyl or alkenyl group, an aromatic group, an alkylaryl, a halogen, a hydrogen, (e) Y, which can the same as or different from X, is a C1 to C4 alkyl or alkenyl group, an aromatic group, an alkylaryl, a halogen, a hydrogen, and (f) A- is non-coordinated or loosely coordinated bulky anion.
