Abstract: In the prepn. of a modified Ti congt. component of a Ziegler catalyst for the polymerisation of 3-6C monoolefins by dry grinding in a vibratory ball mill (a) a Ti cpd. of formula tiCl3. nAlCl3 (n = 0 to 0.7) and (b) a P cpd. of formula OmPX3 in which m = O or 1, X = R, OR or NR2 and R is alkyl-, aryl, -alkaryl- or aralkyl with 24C using molar ratio of (a):(b) = 1:0.01 to 1:1, mill acceleration = 30 to80 m.sec.-2, the improvement comprises reacting the dry ground product in the absence of thinning agents and without grinding and in intimate contact with 0.05-100 times its wt. of an Al cpd. of formula (Alk)2 AlY at 0-125, pref. 55-70 degrees C. for 0.1-100 hr. (where alk is 1-12C alkyl, Y = Cl or Br esp. Cl). The resulting solid is isolated, washed with an inert organic solvent and dried.
