The invention relates to a process for producing semi-aromatic polyethers based on an aliphatic diol, to semi-aromatic polyethers based on an aliphatic diol obtained by said process, and to the use of said semi-aromatic polyethers based on an aliphatic diol for manufacturing membranes, manufactured parts and coatings.

Process for synthesising semi-aromatic polyethers

The present invention relates to a polymer of the aromatic polyether type, containing a biosourced furan diol, to a method for producing said polymer, and to the use of said polymer for producing membranes.

Aromatic polyethers containing a biosourced furan diol

The invention relates to a process for preparing unipolar cation-conducting ionomers from fluoro ionic monomers, to said unipolar cation-conducting ionomers, to the uses thereof, to an electrolytic composition comprising at least one of said unipolar cation-conducting ionomers and to an electrochemical device comprising at least one of said unipolar cation-conducting ionomers, especially as electrolyte.

Process for preparing unipolar cation-conducting ionomers from difluoro ionic monomers

Interpenetrating polymer networks comprising a first network of polymer A formed from monomers, at least one of which contains an aromatic group functionalized with a cation-exchange group, and a second network of polymer B formed from monomers, at least one of which contains a fluorinated group (R). Use of these interpenetrating polymer networks for manufacturing fuel cell membranes.

Interpenetrating polymer networks and uses thereof

The invention relates to the preparation of a crosslinked polymeric film bearing ionic groupings. The process consists in extruding a material comprising at least one prepolymer, in polymerizing said material after extrusion, and in subjecting the extruded material to a chemical reaction for grafting ionic groupings. The prepolymer comprises repeating units each comprising at least one aromatic group GA and at least one functional group GF; it bears at least one group GP which is polymerizable thermally at a temperature greater than the extrusion temperature, or photochemically, and also at least one reactive group GR which allows the grafting of ionic groupings. The films are useful as a membrane for fuel cells or electrodialysis, as an electrolyte of a lithium battery, of a supercapacitor or of an electrochromic device, or as an ion exchange membrane.
