CA 2372030

A family of infection resistant and biocidal polymeric materials incorporates an infection resistant biguanide such as chlorhexidine or polyhexanide pendant to the polymer chain, chemically linked to the polymer through the biguanide group secondary nitrogen atoms. The disclosure extends to the use of such polymeric materials in articles of manufacture and particularly in medical devices, and the preparation of the materials as polymer resins from which articles can be made, as solutions and emulsions which can be used for coating performed articles, and in situ on the surface of preformed polymeric articles.

L'invention porte sur une famille de matériaux polymériques résistant à l'infection et biocides comportant un biguanide résistant à l'infection tel que la chlorhéxidine ou la polyhéxanide pendants de la chaîne de polymères et chimiquement liés aux polymères par les atomes secondaires d'azote du groupe biguanide. L'invention porte également sur l'utilisation desdits matériaux dans des articles manufacturés, en particulier des instruments médicaux, et sur la préparation desdits matériaux sous forme de résines de polymères en solutions ou émulsions dont sont faits lesdits articles pouvant servir au revêtement d'articles préformés, et in situ, à la surface des articles préformés de polymères.
