Abstract: In the prepn. of a Ziegler catalyst component by (1) dry milling a Ti (III) or (IV) chloride, oxychloride or 1-8C alkoxy chloride, or mixed chloride TiCl3. AlCl3, (in which z is less than 5), with a chlorination prod.z of a cpd. of formula (Mea)6.(Meb)2(OH)16CO3(H2O)4, (in which Mea is Mg, Ca, Zn or Mn; Meb is Al or Cr), in wt. ratio 1:2-200 for 5-100 h. under milling acceleration of 4-6m/s2, (2) 1 part of the prod. is then mixed with 0.01-1 part 1-12C alkanol (V) and 1-1000 parts 5-12C alkene (VI) for 0.5-60 mins. at 0-195 degrees C. This is opt. followed by (3) mixing the suspension with a metal cpd. (VIII) of formula MtGs-tEt, (in which Mt is Al or Si; G is a 1-12C hydrocarbon gp. E is Cl, Br, H or -OD; D is as G; s is the valency of Mt; t is 0-2 when Mt is Al, or 0-4 when Mt is Si) until the atomic ratio Ti: mt is 1 : 0.5-20. Used for homo and co-polymerisation of 2-6C alpha-mono-olefins. Polymer yield per unit wt. of Ti is increased, and amt. of fine-grain polymer below 0.1 mm size is reduced.

Abstract: A Ti contg. Ziegler catalyst is prepd. by (1) contacting a finely divided support (I) with a soln. comprising 100 pts. wt. alcohol (II) Z-OH (where Z is satd. 1-8C hydrocarbon), 0.01-6 pts. wt. (calculated as Ti) titanium trihalide where the halogen is Cl and/or Br and 0.01-4 pts. wt. (calculated as Mg) (II) soluble Mg cpd. of formula Mg6Alw(OH)xYy(B-OH)z (where Y is Cl or Br, B is 1-8C satd. hydrocarbon, w is 0-3, x is 0-8, y is 12+3w-z and z is 0-36) to form a dispersion, the wt. ratio of (I) to Ti being 1:0.01-1:0.02 and the wt. ratio of (I) to Mg being 1:0.01-1:0.25; and stripping the dispersion at 200 degrees C but above the m.pt. of (II) to form a solid intermediate prod. This is followed by (2) contacting the intermediate with an acyl halide (III) RCOX (where R is 1-18C satd. hydrocarbon opt. substd. by up to 3 Cl or Br atoms and X is F, Cl, Br or I) opt. dissolved in an organic solvent to form a suspension. The mol. ratio of Ti in the intermediate to (III) is 1:0.01-1:100. Mol. wt. of the polymers can be regulated with lower amts. of mol. wt. regulators esp. H2 and the polymers have improved morphological properties e.g. bulk density and flowability.
