| abstract |
The present invention relates to a copolymer comprising repeating units derived from vinylidene fluoride (VDF) and repeating units derived from at least one (meth) acrylic monomer having the formula (I) [monomer (MA) mole% Wherein R 1 , R 2 and R 3 , which are the same or different from each other, are independently selected from a hydrogen atom and a C 1 -C 3 hydrocarbon group, - R OH represents a hydrogen atom or at least one hydroxyl group refers to C 1 -C 5 hydrocarbon residue (moiety)), and comprises the formula -CF 2 H and / or -CF 2 CH 3 end groups to vinylidene fluoride (VDF) with a repeating unit per 1 Kg of containing (F) in an amount of 30 mmol or more. The present invention also relates to a process for the preparation of the polymer (F) and to the use of the polymer (F) as a binder for electrode production or membrane production. |
