Abstract
A process for forming a vulcanized elastomer composition. An alternating electric field is applied to a first composition comprising vulcanized crosslinked elastomer particles while the composition is compressed to thereby devulcanize the crosslinked elastomer particles and form a second composition comprising devulcanized elastomer particles A crosslinking agent is added to the second composition comprising the devulcanized elastomer particles. The second composition having the crosslinking agent is then vulcanized to form the vulcanized elastomer composition.
