ABSTRACT:
A method of imparting sustained antimicrobial properties throughout a material or substrate using an antimicrobial polymerizable silicon-containing quaternary ammonium salt monomer in a solvent to form a quaternary ammonium salt solution; and mixing the silicon-containing quaternary ammonium salt solution with at least a second monomer or a polymer or coating a solid polymer. Depending on the nature of the second monomer or polymer and the reaction conditions; a copolymer with the first monomer or a homopolymer will form, such that a polymeric material, substrate or formed plastic product comprising the copolymer or homopolymer or blended with the coated concentrate will have sustained antimicrobial properties. This method can be used to make formed plastic products, thin layer films and other products having sustained antimicrobial properties.
