Abstract
Biocidal compositions containing organoselenium compounds are disclosed, as well as methods of producing and using same.
Claims20
A composition, comprising:
- a substrate having a surface;
- and
- a biocidal composition disposed on the surface of the substrate and/or impregnated throughout the substrate, the biocidal composition having the formula:
- wherein the grafting agent is a first functional group that attaches the biocidal composition to the substrate, and wherein the grafting agent is selected from the group consisting of vinyl, acrylate, methacrylate, acrylamide, vinyl, alcohol, amine, carboxylic acid, ester, amide, ether, acid chloride, N-hydroxysuccinimide activated esters, and combinations thereof;
- wherein the linker group is a second functional group that modulates solubility of the biocidal composition, wherein the linker group contains 2-20 carbons and is selected from the group consisting of linear aliphatic chains, branched aliphatic chains, ring structures, and combinations thereof;
- and
- wherein the properties group is a third functional group that modulates physical properties of the biocidal composition, the properties group selected from the group consisting of alcohols, amines, carboxylic acids, and combinations thereof.

A thermoplastic polymer masterbatch composition, comprising:
- a grafted biocidal composition uniformly dispersed in at least one thermoplastic polymer, the amount of the grafted biocidal composition ranging from about 1% to about 20% by weight, the grafted biocidal composition having the formula:
- wherein the grafting agent is a first functional group that attaches the biocidal composition to the substrate, and wherein the grafting agent is selected from the group consisting of vinyl, acrylate, methacrylate, acrylamide, vinyl, alcohol, amine, carboxylic acid, ester, amide, ether, acid chloride, N-hydroxysuccinimide activated esters, and combinations thereof;
- wherein the linker group is a second functional group that modulates solubility of the biocidal composition, wherein the linker group contains 2-20 carbons and is selected from the group consisting of linear aliphatic chains, branched aliphatic chains, ring structures, and combinations thereof;
- and
- wherein the properties group is a third functional group that modulates physical properties of the biocidal composition, the properties group selected from the group consisting of alcohols, amines, carboxylic acids, and combinations thereof.
