Effect of the conditions of activation of magnesium chloride on the substructure and composition of applied titanium-magnesium catalysts of polymerization of ethylene
The effect of the conditions of activation of magnesium chloride on the substructure and composition of applied titanium-magnesium catalysts of polymerization of ethylene was studied; the catalysts were prepared by different methods: (1) by adsorption of TiCl/sub 4/ on highly disperse magnesium chloride prepared from unsolvated butylmagnesium chloride; (2) by adsorption of TiCl/sub 4/ on magnesium chloride activated by grinding; (3) by combined grinding of magnesium chloride with titanium tetrachloride. It was shown that TiCl/sub 4/ reacts with defects in the structure of the magnesium chloride, whose concentration is correlated with the size of the regions of coherent scattering determined from x-ray data.
