Abstract: A method for the controlled removal of water from devulcanized rubber, comprising steps of contacting the devulcanized rubber with a solvent, dissolving the water out of the devulcanized rubber and into solution without removing other components in the rubber such as polymer, separating the devulcanized rubber from the solvent, and drying the devulcanized rubber. By controlling the amount of water that is in the solvent-solution, and/or the amount of time the devulcanized rubber is in contact with the solvent solution the amount of water that is removed can be controlled. By controlling the amount of water that is removed the rheology/viscosity (e.g. G′ and G″) of the devulcanized rubber can be controlled.
