摘要:
Catalytic solids based on titanium trichloride complex, usable for the stereospecific polymerisation of alpha-olefins, obtained by heat treatment, in the presence of a halogenated activating agent, of the liquid material resulting from bringing TiCl.sub.4, pretreated with an electron-donor compound, into contact with a composition (C) corresponding to the general formula AlR.sub.p (Y).sub.q X.sub.3-(p+q) in which R represents a hydrocarbon radical or a hydrogen atom; Y represents a group chosen from --OR', --SR' and --NR'R", in which R' and R" each represent a hydrocarbon radical or a hydrogen atom; X represents a halogen; p is an arbitrary number such that 0
