Abstract
The invention relates to a monomer () carrying an imidazole-type heterocycle (). According to the invention, the chemical structure of said monomer () comprises at least one unit of formula (I) wherein R1 comprises an alkenyl grouping and R2 comprises a grouping for protecting one of the nitrogen atoms of the heterocycle. The invention also relates to a monomer carrying a benzimidazole-type heterocycle, and to protected polymers obtained from said monomers, deprotected polymers produced by the protected polymers, a proton exchange membrane based on deprotected polymers, and a fuel cell provided with said membrane. Furthermore, the invention relates to methods for producing the above-mentioned monomers and polymers.
