Abstract

PURPOSE:To reduce the operating cost as well as to improve the contact efficiency of a polymer with a solvent, by combining a polymer introducing chamber, a solvent removing pipe, a chopping rod, a melted polymer inlet, a solvent outlet, a melted polymer outlet, and a solvent inlet. CONSTITUTION:A melted polymer to be purified is continuously introduced into a polymer introducing chamber 12 via a polymer inlet 1 at the upper part of a hollow cylindrical vessel 5, and allowed to flow down through polymer dispersing holes 8 to the lower part. On the other hand, a solvent is introduced from solvent dispersing nozzles 7 via a solvent inlet 2 at the lower part of the hollow cylindrical vessel and a solvent introducing pipe 6, and comes into contact with the method polymer while ascending in the hollow cylindrical vessel 5, whereby impurities in the melted polymer are extracted with the solvent and the solvent is removed through a solvent outlet 4 via a solvent removing pipe 9. The purified polymer is removed from a polymer outlet 3. By providing a rotating chopping rod 14 near the outlets of the polymer dispersing holes 8, the polymer is made into finely divided particles that fall through the solvent, whereby the extraction efficiency is further improved.
