Patent

CA 2408191

The invention relates to biocidal polymers with a guanidine salt base, characterised in that they are representatives of the series of polyoxyalkylene guanidines and their salts and in that they represent a product of the polycondensation of the guanidine salt with diamines containing polyoxyalkylene chains between two amino groups. Apart from having a strong bactericidal effect, these novel polymer products have relatively low toxicity and high hydrophilicity, dissolve quickly and completely in water and have high relative molecular mass values and distinctive characteristics of polymeric surface-active substances.

L'invention concerne des polymères biocides à base de sels de guanidine, se caractérisant par le fait qu'ils sont des représentants de la série de la guanidine polyoxyalkylène et de ses sels, et qu'ils constituent un produit de polycondensation du sel de guanidine avec des diamines, qui contiennent des chaînes de polyoxyalkylène entre deux groupes amino. Outre un fort pouvoir bactéricide, ces nouveaux produits polymères présentent une toxicité relativement faible, une haute hydrophilie, une aptitude à la dissolution rapide et complète dans l'eau, des valeurs accrues de masse moléculaire relative et des qualités marquées de substances tensioactives polymères.
