Abstract
A biocompatibilizing process in which the surface of a material in need of being biocompatibilized is coated with a copolymer formed by radical polymerization of ethylenically unsaturated monomers comprising a zwitterionic monomer having a sulphobetaine group and a comonomer having a group selected for providing a stable coating of polymer on the said surface. The comonomer may have a hydrophobic group for binding to oppositely charged ionic groups at the surface or a reactive group for forming a covalent bond with functional groups at the surface and/or for forming cross-links in the polymer coating.
