Abstract
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 surfaces 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.
