Abstract:
1. A polymeric composition having antimicrobial properties, the polymeric composition comprising: a crosslinked chemical combination of (i) a polymer having side chains along a backbone forming the polymer, at least two of the side chains containing an amino group, (ii) an antimicrobial agent selected from the group consisting of quaternary ammonium compounds, gentian violet compounds, substituted or unsubstituted phenols, biguanide compounds, iodine compounds, and mixtures thereof, and (iii) a crosslinking agent containing at least two functional groups capable of reacting with the amino groups; wherein the polymer is a polyamide, and the polymer is synthesized by (i) reacting a monomer selected from the group consisting of unsaturated carboxylic acids, esters of unsaturated carboxylic acids, anhydrides of unsaturated carboxylic acids, and mixtures thereof, and a first amine to form an intermediate reaction product, wherein the first amine is selected from the group consisting of RNH 2 , RR 1 NH, polyalkylene polyamines, and mixtures thereof, and (ii) reacting the intermediate reaction product and a second amine to form the polyamide, wherein the second amine is selected from the group consisting of R 2 NH 2 , R 2 R 3 NH, polyalkylene polyamines, and mixtures thereof, wherein R, R 1 , R 2 and R 3 can be the same or different and each contain between about 1 and 50 carbon atoms and are optionally substituted with heteroatoms oxygen, nitrogen, sulfur, and phosphorus or combinations thereof: and at least one of the selected amines includes at least two amino groups.
