Abstract

Procedeul pentru polimerizarea alfa-olefinelor consta în faptul ca monomerii se aduc în reactie în prezenta unui catalizator constînd din clorura de magneziu sau mangan, produsul de reactie dintre triclorura de aluminiu si un donor de electroni reprezentat de eterii alchilici ai acizilor carboxilici sau eterii alchil-arilici în care grupa alchil contine pîna la 7 atomi de carbon si, eventual, un agent de deshidratare.
