摘要 |
A method of producing sulfonated polyester compounds suitable for use as a soil releasing agent and/or textile sizing agent in which a sulfonated acid or ester is reacted with a hydroxy-containing compound to form a sulfonated hydroxy terminated ester which then undergoes a transesterification reaction with a poly(ethylene) terephthalate based polyester followed by polycondensation to form the desired sulfonated polyester compound.
