Abstract

Invenţia se referă la un procedeu de preparare a unui sistem catalitic pentru obţinerea de copolimeri etilen-propilenici. Procedeul de preparare a unui sistem catalitic constă în aceea că, într-o primă etapă, se impregnează cu o soluţie de hidrocarburi sau halohidrocarburi un suport inert, alcătuit dintr-un compus de vanadiu având starea de oxidare cuprinsă între 3 şi 5, într-o a doua etapă, eventual se îndepărtează solventul folosit în prima etapă de pe suportul impregnat, într-o a treia etapă, se tratează suportul impregnat cu vanadiu, rezultat din prima sau a doua etapă, cu o soluţie de hidrocarbură a unui compus având formula generală (I): RAlX, în care R este un radical alchil C, X este un halogen, n + m = 3 şi m este un număr întreg a cărui valoare este cuprinsă între 0 şi 2, etapa a treia realizându-se într-o atmosferă de etilenă sau alfa-olefine, raportul molar dintre aluminiul din etapa a treia şi vanadiu, din prima etapă, fiind 1:1...6:1, iar în final, se separă şi se purifică, eventual, catalizatorul cu conţinut de vanadiu rezultat în etapa a treia.
