Abstract
A catalyst component for polymerizing alphaolefins is prepared by reacting in an inert solvent (a) > 1/6 \sE 1/3 mol. R3Al2X3 or > 1/4 \sE 1/2 mol. RAlX2, with the equimolecular proportion of AlR3, or (b) > 1/6 \sE 1/3 mol. AlX3 with twice this molecular proportion AlR3, or (c) m mol. R3Al2X3 with 1-2m mol. AlR3 (m is \sF 1/3 <\ba1/2 ), or (d) n mol. RAlX2 (n is \sF 1/2 <1), or n1 mol. AlX3 (n1 is 1/3 to 1/2 ) with 1-n (or 1-n1) mol. AlR3; said component is reacted with TiX4 at -80 DEG C. to +40 DEG C., the reaction product heated at 40-150 DEG C. and 0.1-1.5 mols. AlR3 (calculated on RAlX2, in the catalyst suspension) is added. In the formula R=alkyl, X=halogen. Examples describe the polymerization of ethylene and propylene; other monomers mentioned are butene-1, pentene-1, 3-methylbutene-1, 3,3-dimethylbutene-1, 4,4-dimethylpentene-1, 3- and 4-phenylbutenes-1, 4- p-chlorophenylbutene-1, styrene, butadiene and isoprene. Mixtures of such monomers may be copolymerized.
