Abstract (en)
[origin: WO9707141A1] In the present invention, catalyst systems with a high degree of polymerisation are described which contain at least one catalyst constituent of general formula (I): RnMXm, in which M<1> is Ti, Zr or Hf, R<a> is C5 (R<1>, R<2>, R<3>, R<4>, R<5>) or C6 (R<1>, R<2>, R<3>, R<4>, R<5>, R<6>) wherein R<1>, R<2>, R<3>, R<4>, R<5> and R<6> are identical or different, and a hydrogen atom, a C1-C20 alkyl group, a C1-C10 alkoxy group, a C1-C10 fluoroalkyl group, a C6-C20 aryl group, a C6-C10 aryloxy group, a C2-C10 alkenyl group, a C6-C10 fluoroaryl group, a C7-C40 arylalkyl group, a C7-C40 alkylaryl group, a C8-C40 arylalkenyl group, a silyl group, a germyl group, or adjacent groups R<1>, R<2>, R<3>, R<4>, R<5> and R<6> which form with the connecting atoms thereof a ring system; R<b> is one fluorine atom when m = 1, at least one fluorine atom when m > 1 and can be identical or different, and be at least one hydrogen atom, a C1-C20 alkyl group, a C1-C10 alkyoxy group, a C1-C10 fluoroalkyl group, a C6-C20 aryl group, a C6-C10 aryloxy group, a C2-C10 alkenyl group, a C6-C10 fluoroaryl group, a C7-C40 arylalkyl group, a C7-C40 alkylaryl group, or a C8-C40 arylalkenyl group, an OH group, a NR<7>2 group or SR<8>1 group, wherein R<7> and R<8> are a C1-C20 alkyl group, a C1-C10 alkoxy group, a C1-C10 fluoroalkyl group, a C6-C20 aryl group, a C6-C10 aryloxy group, a C2-C10 alkenyl group, a C6-C10 fluoroalryl group, a C7-C40 arylalkyl group, a C7-C40 alkylaryl group, a C8-C40 arylalkenyl group, a silyl group, a germyl group or a halogen atom, m and n are integers, m + n = 2 to 4, and m is at least 1.
