Abstract:
A process for manufacturing a dispersion of a vinylidene fluoride (VDF) thermoplastic polymer [polymer (F)], said process includes polymerizing VDF in an aqueous phase that includes: at least one surfactant selected from the group consisting of non-fluorinated surfactants [surfactant (HS)] and fluorinated surfactants having a molecular weight of less than 400 [surfactant (FS)]; and at least one functional (per)fluoropolyether (functional PFPE) comprising at least one (per)fluoropolyoxyalkylene chain [chain (R′ F )] and at least one functional group, said functional PFPE having a number average molecular weight of at least 1000 and a solubility in water of less than 1% by weight at 25° C., wherein said functional PFPE is present in the aqueous phase in an amount of 0.001 to 0.3 g/l.

Claim (Index 15):
A process for manufacturing a dispersion of a vinylidene fluoride (VDF) thermoplastic polymer [polymer (F)], said process comprising polymerizing VDF in an aqueous phase comprising:\n at least one surfactant selected from the group consisting of non-fluorinated surfactants [surfactant (HS)] and fluorinated surfactants having a molecular weight of less than 400 [surfactant (FS)] selected from the group consisting of:\n surfactant (FS) complying with formula (IA) here below:\n R f \u2014(OCF 2 CF 2 ) k-1 \u2014O\u2014CF 2 \u2014COOX a \u2003\u2003(IA) \n \n wherein R f  is a C 1 -C 3  perfluoroalkyl group comprising, optionally, one or more ether oxygen atoms, k is 2 or 3 and X a  is selected from a monovalent metal and an ammonium group of formula NR N 4 , wherein R N , equal or different at each occurrence, is a hydrogen atom or a C 1 -C 3  alkyl group; and \n surfactant (FS) complying with formula:\n R FS -E-Y r  \n \n wherein: Y r  is an anionic functionality; \n wherein E is a C 4 -C 24  hydrocarbon non fluorinated divalent group, possibly comprising one or more catenary oxygen atom(s); and \n wherein R FS  is a \u2014OR FS f  group, a \u2014N(R FS f ) 2 , or a \u2014OAr(R FS f ) r  group, wherein R FS f , equal to or different from each other at each occurrence, is a C 1 -C 6  perfluoroalkyl group, Ar is an aromatic moiety (e.g. a phenyl group), and r is an integer of 1 to 3; and \n at least one functional (per)fluoropolyether (functional PFPE) comprising at least one (per)fluoropolyoxyalkylene chain [chain (R\u2032 F )] and at least one functional group, said functional PFPE having a number average molecular weight of at least 1000 and a solubility in water of less than 1% by weight at 25\u00b0 C., wherein said functional PFPE is present in the aqueous phase in an amount of 0.001 to 0.3 g/l.
