Patent

CA 2384427

The invention relates to antimicrobial polymer, which can be obtained by copolymerisation of a monomer of formula (I) where R1 = -H or -CH3, R2 = branched or straight chain aliphatic hydrocarbon radical with 1 to 5 carbon atoms, Y=NR3R4, N+R3R4R5 X-R3, R4, R5 = H, a branched or straight chain aliphatic hydrocarbon radical with 1 to 5 carbon atoms, whereby R3, R4 and R5 are identical or different and X- CH3SO-4, NO-3, F-, Cl-, Br-, I-, CH3CH2-, NO2-, NO-, CN-, SCN-, CNO-, ClO-, ClO2-, ClO3-, ClO4-. ClO4- with other aliphatic, unsaturated monomers. The invention also relates to a method for production of said polymers. Said polymers can also be produced by graft copolymerisation of a substrate, whereby a covalently bonded coating is obtained on the substrate surface. The inventive antimicrobial polymers can be used inter alia as microbiocidal coatings on hygiene articles or in the medical field and in paints or protective coatings.

L'invention concerne des polymères antimicrobiens, obtenus par copolymérisation d'un monomère de formule (I) avec d'autres monomères insaturés aliphatiquement, et leur procédé de fabrication. Dans la formule (I), R?1¿ représente -H ou -CH¿3?, R?2¿ représente un reste hydrocarbure aliphatique ramifié ou non ayant 1 à 5 atomes de carbone, Y représente NR?3¿R?4¿, N?+¿R?3¿R?4¿R?5¿ X?-¿, R?3¿, R?4¿ et R?5¿ représentent H, un reste hydrocarbure aliphatique ramifié ou non ayant 1 à 5 atomes de carbone, R?3¿, R?4¿ et R?5¿ pouvant être identiques ou différents, et X?-¿ représente CH¿3?SO?-¿¿4?, NO?-¿¿3?, F?-¿, Cl?-¿, Br?-¿, I?-¿, CH¿3?CH¿2??-¿, NO¿2??-¿, NO?-¿, CN?-¿, SCN?-¿, CNO?-¿, ClO?-¿, ClO¿2??-¿, ClO¿3??-¿, ClO¿4??-¿. Les polymères selon l'invention peuvent également être obtenus par copolymérisation par greffage d'un substrat, un revêtement lié par covalence étant obtenu sur la surface du substrat. Les polymères antimicrobiens selon l'invention peuvent être utilisés comme revêtement microbicide, par exemple sur des articles d'hygiène ou dans le domaine médical, ainsi que dans des peintures ou des peintures de protection.
