Abstract
Procedeu de polimerizare a alfa-olefinelor, la o temperatura între 15,5 si 100 degree C, în prezenta unui catalizator care cuprinde: o prima componenta formata din amestecarea tetraclorurii de titan, a unei baze Lewis, a clorurii de magneziu si, facultativ,a durenului; o a doua componenta constituita din trialchilaluminiu avînd grupe alchil cu 1...12 atomi de carbon; o a treia componenta reprezentînd o baza Lewis.A process for the polymerization of alpha-olefins at a temperature of between 15.5 and 100 ° C in the presence of a catalyst comprising: a first component consisting of mixing titanium tetrachloride, a Lewis base of magnesium chloride and, optionally, of the dragon; a second component consisting of trialkylaluminum having alkyl groups of 1 to 12 carbon atoms; a third component representing a Lewis base.
