ABSTRACT:
This invention provides a method of controlling the pollution in a microwave devulcanization process consisting of passing particles of sulfur-vulcanized elastomer containing polar groups through a microwave energy devulcanization device to generate heat in the devulcanization of said particles whereby said particles exits said device at a temperature in excess of 260.degree. C., feeding said particles from the devulcanization device to feed input of an extruder, extruding said particles to exit the extruder at a temperature of about 90.degree. to 125.degree. C. as an extrudate. The extrudate can be used per se as a compounding stock or sent to a mill to be sheeted and stored until needed.
