Patent ID: 8652499

Claim:
A medical antimicrobial composition comprising an ammonium group-containing polymer compound dispersed in a siloxanyl structure-containing polymer, wherein the ammonium group-containing polymer compound has a structure obtained from the ammonium salt monomer of general formula (f): where R 1 is a substituted or non-substituted alkyl group with 1 to 30 carbon atoms; R 2 to R 7 are, respectively independently, a substituent group selected from hydrogen, substituted or non-substituted alkyl group with 1 to 20 carbon atoms, and substituted or non-substituted aryl group with 6 to 20 carbon atoms; R 2 and R 3 may also form a ring; and X − is a given anion, and wherein at least one component of the siloxanyl structure-containing polymer has a structure obtained from a siloxanyl monomer of general formula (a): M-L-Sx (a) where M is a radical polymerizable group; L is a substituted or non-substituted divalent organic group with 1 to 20 carbon atoms; and Sx is a siloxanyl group.
