Abstract
An antimicrobial polymer is disclosed containing silicon-containing quaternary ammonium groups, the polymer including in its structure repeating units of Formula II:R3N+R0nSiX′4-nY− (II)wherein each R and each R0 is independently a non-hydrolysable organic group; each X′ is —OR′, —OH or —O—Si, wherein R′ is an alkyl group of 1 to about 22 carbon atoms, or an aryl group of 6 carbon atoms; n is an integer of 0 to 3; and Y is an anionic moiety suitable to form the salt of the repeating units of Formula II. Also disclosed are methods of making such a polymer and imparting sustained antimicrobial properties to a substrate using the polymer.
