Use of star prepolymers with at least four water-soluble polymer arms having terminal reactive groups for producing a bacteriostatic finish on surfaces, e.g. medical equipment, implants or contact lenses

摘要

Star prepolymers with at least four water-soluble polymer arms having terminal reactive groups are used for producing a bacteriostatic finish on surfaces. An independent claim is also included for producing a bacteriostatic finish on surfaces by coating the surface with an ultrathin hydrogel-forming coating comprising a star prepolymer with at least four water-soluble polymer arms and crosslinking the prepolymer molecules through the ends of the polymer arms.
