Abstract:
A process for synthesizing a polymer bearing at least one phosphonate group in the polymer chain is provided. The process comprises at least the reaction of a starting polymer bearing at least one nucleophilic function in the polymer chain with at least one electrophilic compound bearing both a phosphonate group and an electrophilic function. The electrophilic function is selected from the halide function, the acyl halide function, the ester function, the carboxylic acid function and the isocyanate function.
