<p>Process for devulcanizing a rubber, which rubber is obtained by vulcanizing with the aid of a sulphur-containing compound a copolymer which contains ethylene monomer units, monomer units of an α-olefin and monomer units of a polyunsaturated compound, by heating the rubber to such elevated temperature that devulcanization occurs and a recyclable product is obtained. Monomer units of a polyunsaturated compound are monomer units according to the formula X-R0, where: X is a group having 2-20 C atoms, which group can polymerise with the aid of a co-ordination catalyst, R0 is a chain having 2-30 C atoms and containing at least one double carbon-carbon bond, with none of the C atoms of the double bond forming part of a ring structure.</p> |
