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.
