Abstract: A Ti-contg. catalyst component for Ziegler catalysts is prepd. by grinding (I) a solid Ti cpd. chosen from (oxy)chlorides or 1-8C alkoxy chlorides of tri- to tetravalent Ti or TiCl3.Z(AlCl3) (where Z is 0.5) and (II) a halogen cpd. prepd. by heating a cpd. of formula (MII)6(MeIII)2(OH16)(CO3)(1(H2O)4 (where MeIII is Al or Cr and MII is Mg, Ca, Zn or Mn) for 1-100 hrs at 150-600 degrees C and then chlorinating to a Cl content of 40-76 wt.%. (I) and (II) are ground in a wt. ratio of (I):(II) of 1:200-1:2 for 5-100 hrs. at a grinding speed of 4-6 m/s2. The process is characterised by forming a suspension of the above prod. (III), a 1-12C alkanol (IV) and a 5-12C alkane (V) in a wt. ratio of (III):(IV) of 1:0.01-1:1 and wt. ratio of (III):(IV) of 1:1-1:1000, mixing the suspension continuously for 0.5-60 min. at 0-195 degrees C and reacting an acyl halide (VI) RCOX (where R is a satd. 1-18C hydrocarbon gp. which can be opt. substd. by up to 3 Cl or Br atoms and X is Cl, Br, F or I), with the suspension until the atom ratio of Ti in the suspension to halogen in (VI) is 1:0.01-1:100. The catalyst has overall improved properties.
