Abstract: Polymers with non-leaching antimicrobial activity and their use as surface coatings or bulk resins for medical devices. The antimicrobial polymers are prepared with antimicrobial moieties covalently bonded to a polymer chain end or to a polymer backbone at a side chain end. The antimicrobial moiety-containing endgroups include surface active (or surface assembling) moieties which promote enrichment of antimicrobial endgroups at the polymer surface and thus formation of an antimicrobially active surface. Polymers with built-in antimicrobial endgroups can be used as bulk resins, as antimicrobial additives, or as infection preventative coatings in the manufacture of medical devices (e.g., catheters, vascular access devices, peripheral lines, IV sites, drains, gastric feeding and tubes, and other implantable devices).

Abstract: Polymers whose surfaces are modified by endgroups that include amphipathic surface-modifying moieties. An amphipathic endgroup of a polymer molecule is an endgroup that contains at least two moieties of significantly differing composition, such that the amphipathic endgroup spontaneously rearranges its positioning in a polymer body to position the moiety on the surface of the body, depending upon the composition of the medium with which the body is in contact, when that re-positioning causes a reduction in interfacial energy. An example of an amphipathic surface-modifying endgroup is one that has both a hydrophobic moiety and a hydrophilic moiety in a single endgroup. For instance, a hydrophilic poly(ethylene oxide) terminated with a hydrophilic hydroxyl group is not surface active in air when the surface-modifying endgroup is bonded to a more hydrophobic base polymer.
