Abstract

Procedimento per effettuare la vulcanizzazione senza zolfo di elastomeri consistente nell'epossidare ad un grado prefissato un elastomero, per esempio gomma naturale (NR), nel preparare una mescola includente l'elastomero epossidato, eventuali altri elastomeri e una quantità prefissata di almeno un composto di formula R1 - R - R2dove R è arilene, alchilene, alchenilene, sostituito o non, o una miscela degli stessi e dove R1 e R2 sono indifferentemente un gruppo carbossilico, un gruppo amminico o un gruppo solfonico o clorosolfonico, e nel trattare successivamente a caldo e sotto pressione la mescola così preparata.
