    Abstract: La invención se refiere a poliésteres ramificados con grupos sulfonato. Los poliésteres se pueden obtener al hacer reaccionar los componentes A, B, opcionalmente C y opcionalmente D en poliésteres ramificados, en donde el componente A se selecciona a partir del grupo que consiste de ácidos dicarboxílicos a,ß-olefínicamente insaturados, el componente B se selecciona a partir del grupo que consiste de alcoholes disfuncionales o funcionales superiores, el componente C opcional se selecciona a partir del grupo que consiste de ácidos carboxílicos disfuncionales o funcionales superiores y ácidos hidroxicarboxílicos sin enlaces a,ß-olefínicamente insaturados, y el componente D opcional se selecciona a partir de los compuestos de la fórmula CH3(-O-CH2-CH2)n-OH, con la condición de que si sólo se seleccionan alcoholes disfuncionales como componente B, el componente C está presente durante la reacción y se selecciona a partir de los ácidos carboxílicos trifuncionales o funcionales superiores y los ácidos hidroxicarboxíficos trifuncionales o funcionales superiores sin enlaces a,ß-olefínicamente insaturados. Los poliésteres ramificados obtenidos posteriormente reaccionan con sulfito de hidrógeno, la cantidad molar de sulfito de hidrógeno siendo a lo mucho 95% molar, con respecto a la cantidad de ácidos dicarboxílicos a,ß-olefínicamente insaturados.
