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 emulsions 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.
On forme des émulsions aqueuses stables, sans utiliser de solvants organiques volatiles et à l'aide d'un traitement à basse énergie, avec un nouveau siloxane de fluorocarbure polymère représenté par la formule: R¿1?-[-OSi(R¿a?)(OR¿1?)]¿x?-[-OSi(R¿b?)(OR¿1?)]¿y?-[-OSi(R¿c?)(OR¿1?)]¿z?-OR¿1? ainsi qu'avec des structures ramifiées polymères correspondantes; dans cette formule R¿a? est un radical perfluoroalcoyle, R¿b? un radical aminoalcoyle ou aminoalcoyle substitué et R¿c? un radical hydrocarbyle, hydrocarbyle phényle substitué, phényle substitué, ou cyanoalcoyle. Ces émulsions s'avèrent être fortement hydrolysées en solution sans entraîner de précipitation par condensation intramoléculaire et, lorsqu'on les applique sur des substrats, elles ont la propriété de repousser à la fois l'eau et l'huile, ainsi que celle de réduire la friction.
