Process for the manufacture of shaped structures with improved dye affinity |
| abstract |
IN THE MANUFACTURE OF COPOLYESTERS FROM TEREPHTHALIC ACID OR THE LOW MOLECULAR WEIGHT ALKYL ESTERS THEREOF AND ETHYLENE GLYCOL, DEFINITE MERCAPTALS AND/OR THIOKETALS ARE INCORPORATED INTO THE MACROMOLECULE BY ESTER LINKAGE. THE POLYESTERS ARE SHAPED FROM THE MELT AND SULFONIC ACID GROUPS ARE PRODUCED IN THE SHAPED STRUCTURES BY AN OXIDATIVE AFTER-TREATMENT. THE STRUCTURES HAVE A HIGH AFFINITY FOR CATIONIC SUBSTANCES. |
