Abstract
The subject invention discloses curable polymeric N-halamine precursors which are useful for forming an antimicrobial surface coating on an object or article of manufacture. The present invention more specifically reveals a cross-linkable, water soluble polymer which is particularly useful for coating substrates and which can be activated to provide such substrates with antimicrobial and/or odor reducing characteristics, said cross-linkable polymer being comprised of amine, amide, or imide group containing repeat units and epoxide or methylol group containing repeat units, wherein the ratio of amine, amide or imide group containing repeat units to epoxide or methylol group containing repeat units is at least 2:1.
Claims12
A cross-linkable, water soluble polymer, said cross-linkable polymer having the structural formula:
- wherein, R1, R2, and R3 can be the same or different and are independently selected from hydrogen atoms and alkyl groups containing from 1 to 10 carbon atoms;
- wherein p is an integer ranging from 0 to about 10;
- wherein m and n are integers ranging from 10 to about 1,000,000;
- wherein o is an integer ranging from 0 to about 1,000,000;
- wherein x1 represents a chlorine atom, wherein x2 is selected from hydrogen atoms and chlorine atoms;
- wherein the ratio of amide containing repeat units to epoxide group containing repeat units is at least 2:1, and wherein the different repeat units are distributed throughout the polymer in an essentially random order, and wherein said cross-linkable polymer can be used for coating substrates and can be activated to provide such substrates with antimicrobial and/or odor reducing characteristics.
