| abstract |
R représente un radical hydrocarboné ou un atome d'hydrogène; Y représente un groupement choisi parmi -OR', -SR' et NR'R'' dans lesquels R' et R'' représentent chacun un radical hydrocarboné ou un atome d'hydrogène; X représente un halogène; p est un nombre quelconque tel que 0 < p < 3; q est un nombre quelconque tel que 0 < q < 3; la somme (p + q) étant telle que 0 < (p + q) ≦3.Catalytic solids based on complexed titanium trichloride, usable for the stereospecific polymerization of alpha-olefins obtained by heat treatment, in the presence of a halogenated activating agent, of the liquid material resulting from the contacting of TiCl₄, pretreated with a electron donor compound, with a composition (C) corresponding to the general formula AlR p (Y) q X 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 any number such that 0 <p <3; q is any number such that 0 <q <3; the sum (p + q) being such that 0 <(p + q) ≦ 3.n n n These catalytic solids with adjustable porosity make it possible to manufacture a wide range of propylene polymers, in particular so-called "block" copolymers of propylene and ethylene. |
