Abstract

Abstract Novel polyoxyalkylene fluoroalkyltrimellitate compounds are disclosed that are useful for improving the soil release properties of textiles. These compounds may be conveniently prepared by reacting a fluorinated alkyl thiol or amine with trimellitic anhydride monoacid chloride to form a fluorinated trimellitic anhydride intermediate product which is then reacted with a polyoxyalkylene derivative.
