The article discusses the direct devolatilization process of elastomers contained in polymer solutions or polymer emulsion by using solvents of aliphatic or aromatic hydrocarbons. It is emphasized that the new process solution is based on two steps - the continuous main evaporation of the solvent and unreacted mononer, and continuous final devolatilization of the elastomer. Discussion on direct watering process, drying process, as well as finishing processes are also provided.
