Abstract
Antimicrobial activity is imparted to the surface(s) of an apparatus or article by a method, comprising: copolymerizing tertbutylaminoethyl methacrylate with at least one other aliphatically unsaturated monomer in the presence of said apparatus or article by which adhesion of the copolymer to said surface(s) is achieved. In an embodiment of the invention, adhesion of the polymer coating on the apparatus or article occurs by graft copolymerization.
Claims16
An antimicrobial coating composition consisting essentially of an organic solvent selected from the group consisting of ethanol, methanol, methyl ethyl ketone, diethyl ether, dioxane, hexane, heptane, benzene, toluene, chloroform, methylene chloride, tetrahydrofuran and acetonitrile, and dissolved therein an antimicrobial polymer obtained by copolymerization in the presence of an initiator of t-butylaminoethyl methacrylate with one or more other aliphatically monounsaturated monomers other than carboxylic acid-containing monomers, wherein at least 60% by weight of said polymer is from said t.-butylaminoethyl methacrylate.
