Patent

CA 2676461

The invention relates to the use of polymeric guanidinium hydroxides for controlling microorganisms. Said polymeric guanidinium hydroxides are based on a diamine containing oxyalkylene chains and/or alkylene groups between two amino groups, and can be obtained by polycondensing a guanidine acid addition salt with the diamine, resulting in a polycondensation product in the form of a salt which is then converted into the hydroxide form by means of basic anion exchange.

L'invention concerne l'utilisation, en vue de lutter contre des micro-organismes, d'hydroxydes de guanidine polymères à base d'une diamine, contenant des chaînes oxyalkylène et/ou des groupes alkylène entre deux groupes amino, obtenus par polycondensation d'un sel d'addition acide de guanidine avec la diamine, ce qui conduit à un produit de polycondensation sous forme d'un sel qui est ensuite amené, par échange anionique basique, sous la forme hydroxyde.
