Abstract
Medical copolymers are provided which comprise (a) a polymer backbone comprising (i) a plurality of —C═C— groups within the polymer backbone, (ii) a plurality of —R— groups within the polymer backbone, wherein Rcomprises a radical-substituted C2-C10 cyclic or heterocyclic group, or (iii) both a plurality of —C═C— groups and a plurality of —R— groups within the polymer backbone, (b) a plurality of hydrocarbon-based pendant groups along the polymer backbone that comprise a saturated or unsaturated carbon chain of at least four carbons in length, and (c) a plurality of zwitterionic pendant groups along the polymer backbone that comprise a positively charged quaternary ammonium group and a negatively charged phosphate group. Methods of forming such copolymers, medical products that contain such copolymers, and methods of making such medical products are also disclosed.
