Abstract: NOVEL 2,4,6-TRISUBSTITUTED-S-TRIAZINE DERIVATIVES CONTAINING SULFONATE GROUPS ARE USED TO IMPROVE THE DYEABILITY OF SYNTHETIC LINEAR POLYAMIDES, WHEREBY THE DYEABILITY OF THE POLYAMIDES BY BASIC DYESTUFFS IS ENHANCED, WHILE AT THE SAME TIME THE DYEABILITY BY ACID DYESTUFFS IS INHIBITED. THE S-TRAIZINES ARE INCORPORATED IN THE POLYMIDE BY ADDING THEM TO EITHER A POLYAMIDE-FORMING REACTANT OR DIRECTLY TO THE SYNTHETIC LINEAR POLYAMIDE. THE MODIFIED POLYAMIDE CAN BE FURTHER PROCESSED IN THE CONVENTIONAL MANNER.
