摘要: A process for recovering monomers and solvent present in a waste stream including the steps of: (a) providing a waste feed stream containing monomers, solvent and impurities; (b) subjecting the waste feed stream of step (a) to a separation process under conditions for separating the monomers and solvent from the impurities of the waste stream; (c) recovering the monomers and solvent in one or more streams; and (d) passing the one or more of the monomer and solvent streams from step (c) to further processing.
