    摘要： A catalyst system contains (a) a cocatalyst and (b) a bimetallic transition metal compound of formula (I) in which M1 is a transition metal of group IIIb-VIb; radicals Y are the same or different and stand for H, R, OH, NR¿2? or Y is a substituted or unsubstituted butadiene unit; k is an integer; radicals A are the same or different and represent a substituted or unsubstituted cyclopentadienyl ligand of which at least one must be substituted; radicals B are the same or different and represent a bridge; radicals D are the same or different and represent X-R?5¿m; X is bonded to B by covalence and to M2 by co-ordination; X is an element of groups Va or VI of the periodic table of elements; radicals R5 are the same or different and represent H, X, or R, or two radicals R5 form one or more rings with their bonding atoms; m equals 1 or 2; M2 is a metal of groups VIb-Xb of the periodic table of elements; radicals W are the same or different and represent H, R, X, OR or NR¿2?, or W represents a substituted or unsubstituted butadiene unit; j is an integer equal to 0, 1, 2, 3, 4, 5 or 6 which corresponds to the valence of the transition metal atom M?2¿; L is a neutral donor ligand; and i is an integer from 0 to 10.

    摘要： A polymerization catalyst and a method of polymerizing ethylene, other olefins, and alkynes with such catalyst are provided by the present invention. In particular, the polymerization catalyst comprises an active cationic portion of the formula
            LM-R⁺
    wherein M is a Group VIII metal,
    L is a ligand or ligands which stabilize the Group VIII metal, and
    R is H, a hydrocarbyl radical or a substituted hydrocarbyl radical; and
    a stabilizing anionic portion of the formula

    wherein X is F, Cl, a hydrocarbyl radical, a substituted hydrocarbyl radical, or combinations thereof, and
    n is an integer from 1 to 5.
    Polymerization is accomplished by contacting a monomer of ethylene, other olefin or alkyne with the catalyst.
