Abstract
Official abstract text for this publication.
Compositions containing at least one compound of formula Iwhere R1 is a phenolic compound (e.g., simple phenol, creosote, thymol, or carvacrol), and where R2 is a polyamine (e.g., ethylenediamine (EDA), diethylenetriamine (DETA), triethylenetetramine (TETA), tetraethylenepentamine (TEPA), hexamethylenediamine (HDA)); and optionally a carrier; the compositions may additionally contain at least one epoxy resin. Methods for killing microorganisms involving contacting the microorganisms with an effective microorganism killing amount of the above composition. Compositions containing at least one compound produced by a method involving reacting phenolic-branched chain fatty acid methyl ester with at least one polyamine.
First claim
Opening claim text (preview).
We claim: 1. An antimicrobial epoxy polymer comprising a curing agent with structure: where R1 is a phenolic group, and where R2 is a polyamine group. 2. The epoxy polymer of claim 1 wherein R 1 is: 3. The epoxy polymer of claim 1 wherein the polyamine group is: ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine or hexamethylenediamine. 4. A composition comprising at least one compound of formula I where R1 is a phenolic group, and where R2 is a polyamine group; and a carrier. 5. The composition according to claim 4 , further comprising where R1 is 6. The composition according to claim 4 , wherein the polyamine group is: ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine or hexamethylenediamine. 7. A method for killing microorganisms, said method comprising contacting said microorganisms with an effective microorganism killing amount of the composition according to claim 1 . 8. The method according to claim 7 , wherein said microorganisms are selected for the group consisting of Gram-positive bacteria, Gram-negative bacteria, and mixtures thereof. 9. The method according to claim 7 , where said microorganisms are Gram-positive bacteria. 10. The method according to claim 7 , where said microorganisms are Gram-negative bacteria.
