The invention relates to a method for separating target polymers and their additives from a material containing polymers, as a result of which the recovery both of the target polymers and of the additives is made possible. Based on the principle of a selective precipitation, the target polymer is precipitated and subsequently separated from the additives present in solution and dissolved foreign polymers. The separation of the additives from the solution is effected in a further step.
L'invention concerne un procédé pour la séparation de polymères cibles et de leurs additifs d'un matériau contenant des polymères, ce qui rend possible la récupération des polymères cibles ainsi que des additifs. Le polymère cible est précipité en se basant sur le principe d'une précipitation sélective, puis est séparé des additifs présents dans la solution et des polymères étrangers qui y sont dissous. Les additifs sont séparés de la solution lors d'une autre étape.
