Zusammenfassung:	The invention relates to a method for separating target polymers and their additives from a material containing polymers, enabling the recovery of both the target polymers and the additives. Based on the principle of selective precipitation, the target polymer is precipitated out and then separated fro m the additives and dissolved foreign polymers present in solution. The additives are separated from the solution in another step.
