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

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. Die vorliegende Erfindung betrifft die Verwendung von sternförmigen Polymeren mit hydrophilen Polymerarmen, die an ihren freien Enden eine reaktive funktionelle Gruppe R tragen, zur bakteriostatischen Ausrüstung von Oberflächen.
