Claim 1
Independent Claim
135 words
Process for the polymerisation of alpha-olefines, which process is carried out in the process of an organometallic compound of a metal from groups la, Ila, lib, lllb and lVb of the Periodic Table and a solid catalytic complex prepared by reacting the following with one another: (1) at least one compound (M) chosen from amongst organic oxygen-containing compounds and halogen-containing magnesium compounds; (2) at least one compound (T) chosen from amongst organic oxygen-containing compounds and halogen-containing titanium compounds; and (3) at least one aluminium halide (A), characterised in that the latter is chosen from amongst organo-aluminium chlorides of the general formula AIR n Cl 3-n , in which R is a linear or branched alkyl radical containing from 4 to 18 carbon atoms and n is a number such that 1 < n < 1.5.
Claim 2
Dependent Claim
