Coating compositions contain a copolymer of anradical polymerised zwitterionic monomer, preferably 2-(methacryloyloxyethyl)-2'-(trimethylammonium)ethylnphosphate inner salt, with a hydrophobic comonomer havingna C 6-24 -alkyl group, and a solvent, which consists ofnalcohol, in which the polymer is dispersed. Thencompositions are used to form haemocompatible coatings onnhydrophobic substrates, such as polyethylene,npolypropylene, polyvinylchloride, polytetrafluoroethylenenand steel. |
