A PROCEDURE FOR REMOVING METAL CATALYST RESIDUES FROM SOLUTIONS OF POLYMERS INSOLUBLE IN WATER CONTAMINATED WITH ONE OR MORE OF SUCH RESIDUES. |
| abstract |
METHOD TO ELIMINATE METAL CATALYST RESIDUES FROM POLYMER SOLUTIONS WITH ONE OR MORE EXCESS DICARBOXYL ACIDS, TO PRECIPITATE THE METALS, FOLLOWED BY THE SEPARATION OF THE PRECIPITATES FORMED BY FILTRATION OR CENTRIFUGATION. IT HAS APPLICATIONS FOR THE PURIFICATION OF POLYMER SOLUTIONS RESULTING FROM CATALYTIC HYDROGENATION PROCESSES. |
