Abstract
The invention relates to a series of novel silicone alkoxylated esters which contain terminal carboxyl groups. 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. The compounds of the present invention are prepared by reacting a the hydroxyl group in a silicone polymer with an anhydride.
