Crosslinkable polymers and crosslinked fluoropolymers are prepared from selected fluorinated dienes and monomers containing Br and I. Also disclosed are proton conductive membranes of these crosslinked fluoropolymers.

Crosslinkable fluoropolymer, crosslinked fluoropolymers and crosslinked fluoropolymer membranes

There are provided electrically conducting polymer compositions comprising an electrically conductive polymer or copolymer and an organic solvent wettable fluorinated acid polymer. Electrically conductive polymer materials are derived from thiophene, pyrrole, aniline and polycyclic heteroaromatic precursor monomers. Non-conductive polymers derived from alkenyl, alkynyl, arylene, and heteroarylene precursor monomers. The organic-solvent wettable fluorinated acid polymer is fluorinated or highly fluorinated and may be colloid-forming. Acidic groups include carboxylic acid groups, sulfonic acid groups, sulfonimide groups, phosphoric acid groups, phosphonic acid groups, and combinations thereof. The compositions can be used in organic electronic devices.

Electrically conductive polymer compositions

A fluorinated ion exchange polymer is prepared by grafting at least one grafting monomer derived from trifluorostyrene on to at least one base polymer in a organic solvent/water mixture. These ion exchange polymers are useful in preparing catalyst coated membranes and membrane electrode assemblies used in fuel cells.

Process to prepare stable trifluorostyrene containing compounds grafted to base polymers using a solvent/water mixture

The present disclosure relates to electrically conductive polymer compositions, comprising at least one electrically conductive copolymer; and at least one fluorinated acid polymer, their use in organic electronic devices, and methods for preparation.

Partially fluorinated ionic compounds are prepared. They are useful in the preparation of partially fluorinated dienes, in which the repeat units are cycloaliphatic.
