ABSTRACT:
A non-crosslinked polymer having pendant zwitterionic groups and pendant functional groups can be coated from a coating composition onto a surface having pendant coreactive functional groups and, after coating, may be cured so that covalent bonds are formed between the coreactive functional groups on the polymer and the surface. Alternatively the polymer can be crosslinked after coating, by formation of covalent intermolecular cross-links between coreactive pendant functional groups on the polymer. The zwitterionic pendant groups preferably have, as the anion, a phosphate ester group, and as the cation, a quaternary ammonium group. The polymer coating is stable and provides improved biocompatibility, especially haemocompatibility.
