Abstract

A series of samples exhibiting different catalytic activity and sorption properties was obtained by grinding two basic types of titanium trichloride (TiCl₃.1/3 AlCl₃ and TiCl₃). The samples with co-crystallized AlCl₃ can sorb, under otherwise identical conditions, by an order of magnitude more diethyl ether than those of pure TiCl₃. The amount of sorbed ether increases with its partial pressure and decreases when elevating the temperature of sorption. There is a correlation between the quantity of ether sorbed on TiCl₃ and the catalytic activity of the latter in the propene polymerization. This correlation is, however, different for both examined catalyst types.
