US 5,235,017 A · Fluorine containing silicone polyester compounds

Abstract

The invention discloses novel fluorine containing polyester compounds. Compounds of the invention by virtue of (a) the silicone containing polyester group, (b) the fluorine containing terminal groups and (c) the polyoxyalkylene containing dimethicone copolyol group are extremely efficient lubricating materials when applied to a variety of surfaces and are water dispersible or water soluble depending upon the specific molecule. These materials have a water soluble portion in the silicone backbone which allows for the preparation of water dispersible and water soluble fluorine containing compounds useful in personal care applications as conditioners and softeners. The compounds of the present invention are prepared by reacting a dimethicone copolyol compound with a dicarboxylic acid and a fluorine containing alcohol.
