    摘要: A method is disclosed for preparing an olefin polymerization catalyst of improved particle size from a solution of magnesium containing component and a transition metal containing component which is reacted with an organoaluminum halide compound. The improved particle size is provided by employing the organoaluminum halide compound in conjunction with a silicon compound, such as for example an alkyl silicate or a polysiloxane.

    摘要: New catalysts for the polymerization and copolymerization of olefins are disclosed. The catalysts are prepared from (1) a new class of metal complexes of general formula M.sub.m M'X.sub.2m Y.nE, in which M is Mg, Mn and/or Ca; m is a number from 0.5 to 2.0; M' is Ti, V and/or Zr; X is Cl, Br or I; Y is one or more atoms or groups of atoms of various kinds in an amount such as to satisfy the valence of M'; n is a number from 0.5m to 20m; and E is an electron-donor compound; and (2) organometallic compounds of metals belonging to one of Groups I to III of the Mendelyeev Periodic Table.
