A continuous process and apparatus for removing liquids and/or vapors from elastomeric polymers causes the liquid containing polymer to undergo mechanical working and then a substantial reduction in pressure while contained within a chamber having small vents to atmosphere or a collection housing. Essentially all of the last traces of liquids or vapors are removed in this chamber, the material is cooled by the vaporization of contained liquids, any resulting fine particles are contained and immediately mixed into the material, and the material is subsequently discharged through an extruder section without further significant creating of fine particles in the end product as discharged.
