Abstract

Un sistema catalitico per polimerizzare i monomeri diolefinici è costituito da un sale di un lantanide, un composto mettallorganico di un metallo del gruppo I, II, e III della tavola periodica degli elementi e da un composto metallorganico del boro. I polimeri ottenuti sono caratterizzati dell'avere elevato tenore di unità a concatenamento 1, 4 e rapporto tra le unità 1, 4-cis/1, 4-trans variabile a piacere, ed inoltre una stretta distribuzione dei pesi molecolari.
