摘要

Novel polymeric fluorocarbon siloxane represented by the formula: R1-[OSi(Ra)(OR1)x-[OSi(Rb)(OR1)]y-[OSi(Rc)(OR1)]z-OR1 and corresponding polymeric branched structures wherein Ra is a perfluoroalkyl radical, Rb is an aminoalkyl or substituted aminoalkyl radical and Rc hydrocarbyl, substituted hydrocarbyl phenyl, substituted phenyl or cyanoalkyl radical are shown to form stable aqueous emulsions without the use of volatile organic solvents and by a low energy processing. These emulsion are found to be highly hydrolyzed in solution without leading to precipitation via intermolecular condensation The emulsions when applied to substrates impart both oil and water repellent properties as well as improved lubricity.
