摘要：
Reclaimed rubber for reuse in tires or for asphalt, etc. and obtained by devulcanization treatment of vulcanized rubber from discard tires, etc. has a proportion of sol to gel of 10-80%, a weight-average molecular weight (Mw) of the sol by gel permeation chromatography (GPC) of 20,000-300,000, and a degree of swelling of the gel of 3.0-20.0. A process for reclaiming the vulcanized rubber is also disclosed.
