Abstract:
1. An antimicrobial polymer in the form of a solvent-free solid homopolymer containing silicon-containing quaternary ammonium groups, the homopolymer comprising in its structure repeating units of Formula II: wherein each R and R 0 is independently a non-hydrolysable organic group; each X′ is —OR′ or —OH or has been converted along with another X′ on another of the repeating units to form an —O— linkage between Si atoms of respective repeating units, wherein R′ is an alkyl group of 1 to about 22 carbon atoms, or an aryl group of 6 carbon atoms; and Y is an anionic moiety suitable to form the salt of the repeating units of Formula II, wherein the solvent-free solid homopolymer is in the form of discrete solid particles, wherein the solvent-free solid homopolymer is soluble and sufficiently stable to provide sustained antimicrobial properties to a substrate or formulation comprising the homopolymer dissolved in a solution, and wherein the homopolymer includes a predominant mole percentage corresponding to a T 3 structure.
