Abstract
The invention relates to a series of novel alkoxylated fluoro esters which contain a terminal carboxy group. This class of compounds provides unique solubility in many organic solvents as well as very substantive salts of the carboxylic acid when neutralized with base. In addition, the compounds of the present invention have tremendous spreadability when applied to substrate. The compounds of the present invention are prepared by reacting a the hydroxyl group in a fluoro alcohol with an anhydride.
