CA 2112411

Polymers of one or more radical polymerisable monomers which polymer has pendant groups bearing a centre of permanent positive charge and other pendant groups capable of stably binding the polymer to a surface are useful in the treatment of surfacts to render them biocompatible. The polymers may contain pendant groups which bind the polymer to a surface by physisorption, covalent bonding or ionic interactions. Additionally reactive groups in the polymer may serve as points for attachment of ligands to the polymer when coated on a surface.

Polymères composés de monomères polymérisables à un ou plusieurs radicaux, et présentant des groupes libres comportant un centre de charge positive permanente, et d'autres groupes libres susceptibles de lier de façon stable le polymère à une surface. Ces polymères peuvent être utilisés pour traiter des surfaces afin de les rendre biocompatibles. Ils peuvent contenir des groupes libres qui lient le polymère à une surface par physio-adsorption, fixation covalente ou interactions ioniques. En outre, des groupes réactifs dans le polymère peuvent servir de points de fixation de ligands au polymère lorsque celui-ci est appliqué sur une surface.
