Abstract
The present invention relates to a class of compounds which have superior soil release properties over heretofore known soil release polymers. The compounds are prepared by the reaction of an aromatic hydroxy containing polyester soil release agent with trimellitic anhydride under acid catalysis to produce an aromatic terminal capped carbonyloxy soil release polymer.
