The invention relates to a polymeric antimicrobial composition, method of its production and use. The antimicrobial ionomer composition contains an amino-functional polymer compound, which is a polyethyleneimine with a molecular weight of Mw of 200 to 3,000,000, which is reacted with silver halide, optionally together with a stabilizing component, such as an organic substance containing a sulfamide functional group. The ionomer composition may be prepared by the combined reaction of (i) at least one polyethylene amine and silver halide and optionally at least one organic stabilizing substance or (ii) at least one polyethylene amine, at least one non-halide silver salt or a complex of silver, hydrogen halide and or an alkali metal halide salt and optionally at least one organic stabilizing agent. The presented ionomer composition is suitable for use as an antimicrobial coating, antimicrobial treatment, an antimicrobial additive and an antimicrobial component for the preparation of new antimicrobial materials. |
