FLUOROPOLYMER WITH ANTIBACTERIAL ACTIVITY

摘要

The invention relates to a grafted fluoropolymer onto which is grafted at least one unsaturated monomer of formula in which: A is a -C(=O)-O-, -O-C(=O)-, -C(=O)-NR'- or -(CH<SUB>2</SUB>)<SUB>x</SUB>-C(=O)-NH- group, x being an integer between 1 and 12; R and R' are H or CH<SUB>3</SUB>; B is a linear or branched C<SUB>1</SUB>-C<SUB>20</SUB> alkylene chain, or arylene or alkylarylene chain; W<SUP>+</SUP> is a quaternary ammonium group, a phosphonium group, or a saturated or unsaturated heterocycle comprising a nitrogen atom, chosen from piperidine, piperazine, morpholine, thiomorpholine, 15-thiazole, isothiazole, pyrazole, indole, indazole, imidazole, benzimidazole, quinoline, isoquinoline, benzotriazole, benzothiazole, benzoisothiazole, benzoxazole, benzoxazine, isoxazole, pyrrole, pyrazine, pyrimidine, pyridazine, quinazoline and acridine; 20 X<SUP>-</SUP> is an anion. This fluoropolymer has antibacterial activity.
