Title (EN) POLYMERIZATION OF OLEFINS,IN THE PRESENCE OF A CATALYST
(FR) PROCEDE POUR LA POLYMERISATION D"OLEFINES EN PRESENCE DE CATALYSEUR
Abstract: front page image
(EN)Polymerization of olefins, in particular ethylene, by means of a catalytic system comprising an organic compound of aluminium and a suspension or solution of a magnesium salt in a non-polar organic solvent, the salt having been previously heated and dehydrated in the presence of acetic acid or of acetic anhydride and then brought into contact with the olefin. This catalytic system, absolutely free from transition metals keeps its polymerizing activity without interruption for a long time.
(FR)Polymerisation des olefines, notamment l"ethylene, au moyen d"un systeme catalytique comprenant un compose organique d"aluminium et une suspension ou solution d"un sel de magnesium dans un solvant organique non polaire, ce sel ayant ete prealablement chauffe et deshydrate en presence d"acide et/ou d"anhydride acetique puis mis en contact avec l"olefine. Ce systeme catalytique absolument depourvu de metaux de transition garde son activite polymerisante sans discontinuer pendant une tres longue periode.
