摘要:
Catalyst systems for polymerising C2 to C10-alk-1-enes contain as active components (a) a metallocene complex having the general formula (I), in which the substituents and indexes have the following meaning: M stands for a metal of the secondary group III, IV or V of the periodic table or for a metal from the group of the lanthanides; X stand for halogen, hydrogen, C1- to C10-alkyl, C3- to C10-cycloalkyl, C6- to C15-aryl, alkylaryl with 7 to 15 C atoms or -OR15, in which R15 stands for C¿1? to C1 to C10-alkyl, C6- to C15-aryl, alkylaryl, arylalkyl, fluoroalkyl or fluoroalkyl or fluoroaryl having each 1 to 10 C atoms in the alkyl residue and 6 to 20 C atoms in the aryl residue; n stands for the valency of M, less the number two; R?1 to R14¿ stand for hydrogen, C¿1? to C10-alkyl, C3- to C10-cycloalkyl, which in turn can carry a C1- to C10-alkyl as substituent, C6- to C15-aryl or arylalkyl, whereas if required two adjacent residues may also stand together for cyclic groups having 4 to 15 C atoms, or Si(R?16)¿3, in which R16 stands for C¿1?- to C10-alkyl, C6- to C15-aryl or C3- to C10-cycloalkyl; y?1, y2¿ stand for CH¿2?, C(R?17)¿2, Si(R17)2, Ge(R17)2 or Sn(R17)2, in which R17 stands for C¿1?- to C10-alkyl, C6- to C15-aryl, C3- to C10-cycloalkyl, alkylaryl or Si(R?18)¿3, in which R18 stands for C¿1?- to C10-alkyl, C6- to C15-aryl, C3- to C10-cycloalkyl or alkylaryl; as well as (b) an open-chain or cyclic alumoxane compound having the general formula (II) or (III), in which R?19¿ stands for a C¿1?- to C4-alkyl group and m is an integer between 5 and 30.

Catalyst systems for polymerising C2 to C10 alk-1-enes containing as active components: a) a metallic complex of general formula (I) in which M is a metal of the III, IV or V sub-group of the periodic system or a metal from the lanthanide group; X is fluorine, chlorine, bromine, iodine, hydrogen, C1 to C10 alkyl, C6 to C15 aryl or -OR7, where R7 is C1 to C10 alkyl, C6 to C15 aryl, alkylaryl, arylalkyl, fluoralkyl or fluoraryl with 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical; n is the valency of M minus 2; R1 to R6 are hydrogen, C¿1? to C10 alkyl, 5 to 7 membered cycloalkyl which in turn may have a C1 to C10 alkyl as a substituent, C6 to C15 aryl or arylalkyl in which two adjacent radicals may together stand for cyclic groups having 4 to 15 C atoms, or Si(R?8)¿3 where R8 is C1 to C10 alkyl, C6 to C15 aryl or C3 to C10 cycloalkyl; E1, E2 are, independently, Si(R9)2, Ge(R9)2, Sn(R9)2 or C(R9)2-C(R9)2 where R9 is C1 to C10 alkyl, C3 to C10 cycloalkyl or C6 to C15 aryl; and b) is an open-chained or cyclic alumoxane compound of general formula (II) or (III) in which R10 is a C¿1? to C4 alkyl group and m is an integer from 5 to 30.
