Abstract

L'invention concerne un procédé de production de composés de polyester sulfoné destinés à être utilisés comme agent d'élimination des salissures et/ou comme produit d'encollage textile, dans lequel un acide ou un ester sulfoné est mis à réagir avec un composé contenant un hydroxy pour former un ester sulfoné à terminaison hydroxy, qui est alors soumis à une transestérification avec un polyester à base de poly(éthylène)téréphtalate, suivie d'une polycondensation, pour former le composé de polyester sulfoné voulu.
