The present invention discloses a process for devulcanizing cured rubber into
devulcanized rubber that is capable of being recompounded and recured into useful
rubber products, said process comprising heating the cured rubber to a temperature
which is within the range of about 150 C. to about 300 C. under a pressure
of at least about 3.4106 Pascals in the presence of a mixture
