METHOD AND DEVICE FOR SEPARATING SOLIDS FROM POLYMER SOLUTIONS
The present invention relates to a process for separating a dissolved polymer from solids, wherein the solid is separated off by sedimentation and the sedimented solid is washed in countercurrent with a solvent. The present invention further relates to a process for preparing polymers in a solvent,...

| description | The present invention relates to a process for separating a dissolved polymer from solids, wherein the solid is separated off by sedimentation and the sedimented solid is washed in countercurrent with a solvent. The present invention further relates to a process for preparing polymers in a solvent, whereina) a polymer having a low molecular weight is prepared in solution,b) the solid which is undissolved in the reaction mixture is separated off by sedimentation andc) the mixture which has been freed of the solid is polymerized further until a particular molecular weight has been reached. |
