Abstract

Process for the preparation of vulcanizable mixtures, with self-adhesion values suitable for mounting elastomeric layers in tires, characterized by combining, with vulcanizing agents and normal additives, a composition composed of an elastomeric copolymer of ethylene, an alpha-olefin, especially propylene, and, optionally, one or more dienes chosen from 2-ethylidene-norbornene-5, 2-metalyl-norbornene-5, 6-methyl-4,7,8,9-tetrahydroindene, 5,6-dimethyl -4,7,8,9-tetrahydroindene and 1,4-hexadiene, in proportion of said components such that the ethylene content in the copolymer is between 60 and 80% and preferably between 65 and 75 % by weight, integrating a homogeneous elastomeric copolymer with a maximum level of ethylene without developing polyethylene crystallinity.
