Novel sulfonated hydrodispersible or hydrosoluble polyesters with a molecular weight less than 20,000, having a sulphur content by weight of about 0.5-10 % and a hydroxyl function content, expressed in OH/kg polymer equivalent, greater than 0.2. The polyesters of the invention can be used as finishing or anti-redeposit agents and optionally as detergent agents in rinsing, softening or finishing compositions for washing with or without pretreatment, rinsing or softening or finishing textiles, especially polyester-based textiles.

Nouveaux polyesters sulfonés hydrodispersables ou hydrosolubles de masse moléculaire en nombre inférieur à 20000, présentant une teneur pondérale en soufre de l'ordre de 0,5 à 10 % et une teneur en fonctions hydroxyles exprimée en équivalent OH/kg de polymère supérieure à 0,2. Ils peuvent être utilisés comme agents anti-salissure et/ou anti-redéposition et éventuellement détergents dans des compositions détergentes, dans des compositions de rinçage d'adoucissage ou de traitement anti-salissure, pour le lavage avec ou sans prétraitement, le rinçage, l'adoucissage ou le traitement anti-salissure de textiles, notamment à base de polyesters.
