Abstract
Procedure for the polymerization of alpha-olefins containing at least three carbon atoms, and mixtures of these with ethylene, characterized in that, in its implementation, said polymerization is verified in the presence of catalysts consisting of the reaction products of A) products of addition and/or substitution of electron donor compounds (Lewis bases) with aluminum-alkyls or reaction products of Lewis bases with aluminum-alkyls containing two or more aluminum atoms linked by means of oxygen or nitrogen, said products A) being further characterized in that the organic aluminum compound presented in combination with the Lewis bases, constitutes from 0.01 to monkeys of 1 mole per mole of the starting aluminum compound, with B) products consisting of compounds and/or compositions containing magnesium, titanium, aluminum and halogens and where the atomic ratio halogen/Mg is (see formula) chosen from: I - products obtained by contacting (a1) a halogenated titanium compound with the reaction product among (a2) magnesium compounds, chosen from the alcoholates of the formula X Mg OR, where R is an alkyl radical, cycloalkyl or aryl containing 1 to 20 carbon atoms, X is a halogen atom or is R or RO dialkyl (or aryl) compounds of Mg of the formula R MgR where R has the meaning indicated above, Mg salts of saturated or unsaturated carboxylic acids and magnesium enolates, and (a3) aluminum halides of the AlRnX3-n type, where R has the meaning indicated above, X is a halogen atom and n is a number less than 3, between 0 and 3, and II - reaction products of (b1) aluminum halides of the AlRmX3-m'type, where R and X have the aforementioned meaning is already an integer between 0 and 3, with the reaction products between chosen magnesium compounds among those of the type indicated above with (a2) and magnesium halides and oxy-halides (b2), with titanium alcoholates (b3), optionally in mixture with (b4) aluminum alcoholates.
