Influence of the diene monomer on devulcanization of EPDM rubber
Journal of Applied Polymer Science, 2008AbstractEthylene–propylene–diene rubbers (EPDM) with 2‐ethylidene‐5‐norbornene (ENB), dicyclopentadiene (DCPD), and 1,4‐hexadiene (HD) as third monomers have been vulcanized with peroxide and with a conventional sulfur vulcanization recipe, and their devulcanization was subsequently investigated for recycling purposes.

Devulcanization of nitrile butadiene rubber in nitrobenzene
Journal of Applied Polymer Science, 2004AbstractSulfur‐crosslinked nitrile butadiene rubber (s‐NBR) was found to be devulcanized when it was heated with nitrobenzene at 200°C for 3 h. The tetrahydrofuran (THF)‐soluble fraction from s‐NBR heated with nitrobenzene was purified by reprecipitation with THF/n‐hexane, chloroform/n‐hexane, and THF/n‐hexane systems and was then characterized by ...

Abstract Waste rubber (WR) powder was introduced in a two-roll mill in the presence of various ratios of curatives to develop sheets of devulcanized waste rubber (DWR). The product has been investigated by FTIR, TGA and SEM. A thermoplastic elastomer (TPE) was prepared by blending the obtained DWR with high density polyethylene (HDPE) at different ...

ABSTRACT The effect of the reaction medium and process conditions on the modification of ground tire rubber (GTR) was studied. For this, a polar reaction medium (ethylene glycol) and a nonpolar medium (1‐octadecene) were compared, using hexadecylamine as a devulcanizing agent in a microwave reactor.
