    • 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 —R9— groups within the polymer backbone, wherein R9 comprises a radical-substituted C2-C10 cyclic or heterocyclic group, or (iii) both a plurality of —C═C— groups and a plurality of —R9— 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.
    • 提供医疗共聚物,其包含(a)聚合物主链,其包含(i)聚合物主链内的多个-C≡C-基团,(ii)聚合物主链内的多个-R9-基团,其中R9包含基团 - 取代的C 2 -C 10环状或杂环基团,或(iii)聚合物主链内的多个-C≡C-基团和多个-R9-基团,(b)多个基于烃基的侧基 包括长度为至少四个碳的饱和或不饱和碳链的聚合物主链,和(c)沿聚合物主链的多个两性离子侧基,其包含带正电荷的季铵基和带负电荷的磷酸基。 还公开了形成这种共聚物的方法,含有这些共聚物的医药产品,以及制造这种医药产品的方法。
