The present invention pertains to vinylidene fluoride copolymers comprising recurring units derived from hydrophilic monomers and to their use as binder for electrodes in Li-ion batteries.

High performance binders for lithium battery electrodes

The present invention pertains to a process for the manufacture of a grafted fluorinated polymer comprising at least one grafted side chain comprising one or more glycosidic recurring units [polymer (F)], said process comprising polymerizing:

Hydrophilic vinylidene fluoride polymers

The present invention pertains to a process for the manufacture of a grafted fluoropolymer [polymer (Fg)], said process comprising reacting: A) at least one fluoropolymer comprising at least one functional group selected from the group consisting of a hydroxyl group and a carboxylic acid group [polymer (F)], B) at least one polyoxyalkylene (POA) of formula (I): R&#x2014;(CH&#x2014;O)&#x2014;(CHCHRO)&#x2014;(CH&#x2014;O)&#x2014;R, wherein at least one of Rand Ris a reactive group comprising at least one heteroatom selected from oxygen and nitrogen different from the hydroxyl group, the remaining, if any, being a &#x2014;[O]&#x2014;CHalkyl group, wherein z is 0 or 1, Ris a hydrogen atom or a C-Calkyl group, x and x', equal to or different from each other, are independently 0 or 1, and n is an integer comprised between 2 and 1000, preferably between 5 and 200, C) optionally, in the presence of at least one catalyst, and D) optionally, in the presence of at least one organic solvent (S). The present invention also pertains to grafted fluoropolymers obtained from said process and to uses of said grafted fluoropolymers for manufacturing porous membranes.
