Title:
HYDRO-FLUOROCOMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2012/160135
Kind Code:
A1
Abstract:
The invention pertains to certain hydro-fluorocompounds of the following formula (I): RfO-RH-O-(CH2)m-[CF(X)]n-COOXa wherein: - Xa is H, a monovalent metal (preferably an alkaline metal) or an ammonium group of formula -N(R'n)4, wherein each of R'n, equal to or different from each other, independently represents a hydrogen atom or a C1-6 hydrocarbon group (preferably an alkyl group); - Rf is a C1-C6 (per)fluoroalkyl optionally comprising one or more catenary oxygen atoms, preferably Rf is a group of formula R'f-CH2-, wherein R'f is a C1-C5 perfluorinated group, possibly comprising one or more ethereal oxygens, preferably a C1-C3 perfluorinated group, possibly comprising one or more ethereal oxygens; - RH is a fluorine-free hydrocarbon group optionally comprising one or more catenary oxygen atoms; - X is F or CF3, preferably X is F; - m is 0 or 1; - n is 1 to 3, to a process for the manufacture of said hydro-fluorocompounds, to a method of making fluoropolymers in the presence of said hydro-fluorocompounds, and to fluoropolymer dispersions comprising said hydro-fluorocompound.
