PROCESS FOR PREPARING AN ION-EXCHANGE COMPOSITE MATERIAL COMPRISING A SPECIFIC POLYMER MATRIX AND A FILLER CONSISTING OF ION-EXCHANGE PARTICLES

摘要

The present invention is a method for producing a composite material containing a fluorinated polymer matrix and a filler consisting of ion exchange inorganic particles, comprising the step of synthesizing the particles in situ within the polymer matrix, wherein the matrix comprises at least two types of fluorine. It relates to a process comprising at least one first copolymer consisting of a copolymer having at least one branched maleic anhydride group, one type of which contains fused repeating units.
