Abstract
The present disclosure relates to antimicrobial polymers which impart prolonged antimicrobial activity to a surface or in a solution, the polymers comprising as repeating monomers a polymerizable cyclic moiety forming part of the polymer backbone and an anti-microbial moiety such as a quaternary ammonium moiety in the side chain. The polymer may further comprise polymerizable units of at least one unsaturated monomer having an ethylenically unsaturated double or triple bond.
Claims27
An anti-microbial polymer, comprising polymerizable units of
- i) at least one monomer comprising a polymerizable aromatic moiety containing an aromatic group, wherein the aromatic group is covalently incorporated into the polymer backbone through loss of aromaticity, and wherein the monomer further comprises an anti-microbial moiety, wherein the anti-microbial moiety is a quaternary ammonium moiety or a quaternary phosphonium moiety.
