Patent ID: 8187623

Claim:
A medical product comprising a medical copolymer, said copolymer comprising (a) a polymer backbone that comprises (i) a plurality of —C═C— groups within the polymer backbone, (ii) a plurality of —R 9 — groups within the polymer backbone, wherein R 9 comprises a radical-substituted C2-C10 cyclic or heterocyclic group, or (iii) both a plurality of —C═C— groups within the polymer backbone and a plurality of —R 9 — 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, wherein the copolymer comprises a plurality of monomers selected from wherein R 1 and R 2 are selected from —H, —(CH 2 ) m —OH, —(CH 2 ) m —COOH, —(CH 2 ) p —CH 3 , —(CH 2 ) m —O—(CH 2 ) p —CH 3 , —(CH 2 ) m —CO—O—(CH 2 ) p —CH 3 , —(CH 2 ) m —O—CO—(CH 2 ) p —CH 3 , wherein m is an integer between 0 and 5, wherein p is an integer between 4 and 25, and wherein at least one of R 1 and R 2 is not —H, —(CH 2 ) m —OH or —(CH 2 ) m —COOH.
