Abstract
Microorganisms can contaminate a number of surfaces, such as those of consumer products. The present disclosure describes compositions and methods of manufacturing and using the same for providing biocidal activity on such surfaces. The compounds of the present invention can comprise a sample of a polymer. The polymer can comprise a repeating unit having a side chain that comprises a nitrogen-containing heterocycle. The nitrogen-containing heterocycle can form an N-halamine and exhibit the biocidal activity.

A method of manufacturing a polymeric composition, comprising:
- (a) contacting a first polymer and a second polymer, wherein:
- the first polymer comprises a repeating unit, wherein the repeating unit comprises a nitrogen-containing heterocycle, wherein the nitrogen-containing heterocycle forms an N-halamine when exposed to an electrophilic halogen source, and
- the second polymer does not comprise a side chain that comprises a hydantoin group;
- and
- (b) softening a portion of the first polymer and a portion of the second polymer by application of a stress source, to blend the portion of the first polymer and the portion of the second polymer.
