Abstract

Inventia se refera la un procedeu pentru prepararea unui material de suport eficace pentru componenta de baza de halogenura de titan a unui catalizator complex coordinativ utilizat la polimerizarea alfa-olefinelor care cuprinde fazele urmatoare: contactarea intima a clorurii de magneziu cu un agent de uscare la temperatura ridicata; macinarea clorurii de magneziu pentru a-i activa suprafata; repetarea fazei de contactare si a fazei de macinare, pentru doua sau mai multe cicluri, în care caz, se produce materialul de suport eficace.
