摘要： The invention features methods of separating a polymer from a biomass containing the polymer. In one aspect, the method includes contacting the biomass with a solvent system to provide a residual biomass and a solution. The solvent system includes a solvent for the polymer and a precipitant for the polymer, and the solution includes the polymer, the solvent for the polymer and the precipitant for the polymer. Applying a centrifugal force to the solution from the residual biomass to separate at least some of the solution from the residual biomass. In another aspect, the method includes contacting the biomass with a solvent system to provide a residual biomass and a solution including the polymer and the solvent system; adding a precipitant for the polymer to the solution; and a separating at least some of the solution from the residual biomass after adding the precipitant for the polymer.
