Procedure for preparing detergents, especially of the type that act as detergency builders, that improve the detergent and antiredepositive power of the baths with aqueous washing, water-soluble sulphonated polyesters whose sulfonation is practiced at the level of the unsaturated aliphatic chains, and which replacing the total or partially to polyphosphates or other polyelectrolytes, basic components of the bleaches, as well as antiredeposition agents, characterized in that said water-soluble sulphonated polyesters combined with the usual components of the detergents result from the polycondensation of an aromatic diacid, its anhydride or diester, of an unsaturated aliphatic diacid, its anhydride or a diester of this acid, with a saturated glycol, and the sulfonation which is effected on the unsaturated aliphatic chains results, either from a subsequent sulfonation treatment of the polycondensation product of various components or either of a previous sulfonation of the diester of the unsaturated aliphatic diacid leading to a saturated sulfonated diester, which is then reacted with the other two components of the polycondensation reaction in order to directly obtain the water-soluble sulfonated polyester.
