摘要
(US10342232) A binder, and related processes, has been developed for biological agent defeat formulations. This highly iodinated binder is based on the polymer polyethylene tetraiodoterephthalamide. The materials have been formulated with metal fuel particles, such as aluminum, and various oxidizers, such as metal oxides. The binder-thermite composites may be actuated to initiate oxidation, therein generating heat. Upon thermal decomposition of these materials, iodine, a biocide, is released allowing for sterilization of biological agents.

(US10342232) What is claimed is: 1. A polymer having biocidal substituents, comprising: an iodinated polymer, polyethylene tetraiodotere-phthalamide (PETITA), as shown below, and analogs thereof  wherein said analogs are selected from the group consisting of hexamethylenediamine and other aliphatic, cycloaliphatic, and aromatic diamines. 2. The polymer according to claim 1, wherein said iodinated polymer entraps micron sized particles of at least one of aluminum, other metal fuels, and various oxidizers within the polymer matrix, and gives one of polymer-metal and polymer-thermite composites. 3. The polymer according to claim 2, wherein a layer of fluorinated compound is evaporatively coated on one of said iodinated polymer-metal and said polymer-thermite composite. 4. A polymer having biocidal substituents, comprising: either of the trimers below: or 5. The polymer according to claim 1, wherein said iodinated polymer and said analogs are a trimer, and wherein said trimer is a binder for biological agent defeat formulations. 6. The polymer according to claim 1, wherein said iodinated polymer and said analogs are a trimer, wherein said trimer is a binder for biological agent defeat formulations, wherein the biological agent defeat formulations include an iodinated binder, metal fuel, and an oxidizer, wherein the metal fuel is micron aluminum particles, and wherein the oxidizer is selected from one of metal oxides, fluorinated compounds and iodine pentoxide. 7. A process for making one of a polymer or trimer of claim 1 or 4 having biocidal properties, comprising: dissolving stoichiometric amounts of tetraiodoterephthaloyl chloride, one of ethylene diamine and an analog of the ethylene diamine, and trimethylamine (TEA) into N-Methyl-2-pyrrolidone (NMP) in a dried Schlenk flask under argon atmosphere, wherein the analogs include hexamethylenediamine, and other aliphatic, cycloaliphatic, and aromatic diamines; stirring the Schlenk flask overnight at room temperature; diluting the mixture with water forming a slurry; collecting the slurry as a light yellow solid by vacuum filtration; washing the solid with ethanol and diethyl ether; and crushing the solid and drying it using a high vacuum for giving one of the polymer or trimer in a quantitative yield. 8. The process according to claim 7, wherein said tetraiodoterephthaloyl chloride is synthesized by the steps comprised of:   adding tetraiodoterephthalic acid and an excess thionyl chloride to a dried Schlenk flask connected to a reflux condenser and under argon atmosphere;   stirring and heating the Schlenk flask for 6 h at 100° C.;   removing by evaporation any unreacted thionyl chloride leaving impure tetraiodoterephthaloyl chloride;   dissolving the impure tetraiodoterephthaloyl chloride in anhydrous tetrahydrofuran (THF) to form a dissolved tetraiodoterephthaloyl chloride;   filtering the dissolved tetraiodoterephthaloyl chloride using a cannula tube;   evaporating the THF leaving a tan solid; and   drying by high vacuum to obtain the tetraiodoterephthaloyl chloride in 75% yield. 9. The process according to claim 8, wherein said tetraiodoterephthalic acid (TIPA) is synthesized by the steps comprised of: dissolving terephthalic acid in 20% fuming sulfuric acid in a reaction flask, wherein the flask is vented to a sulfuric acid bubbler, stirred, and heated to a temperature of 100° C.; adding iodine to the reaction flask, and incrementally raising the temperature to 125° C. for 30 min, wherein the flask is wrapped in foil and the temperature is increased to 150° C. for 15 min, 170° C. for 15 min, and 190° C. for 6 h; allowing the reaction mixture to cool overnight; pouring the mixture into ice cold water, washing the flask therein forming a slurry having a pink solid, which is collected by vacuum filtration, wherein the pink solid is impure TIPA; purifying the TIPA by dissolving it in aqueous KOH to a pH of about 10, vacuum filtering, adding NaHSO3 to the filtrate, therein causing the TIPA to precipitate by the addition of concentrated HCl acid to a pH of about 1, vacuum filter the precipitate to dryness and allowing it to air dry overnight; and removing any remaining impurity by triturating the TIPA with acetone at room temperature and in hot methanol, and then vacuum filtering until the TIPA is a white solid at 45% yield. 10. A process for making one of a polymer or trimer of claim 1 or 4 having biocidal properties, comprising: dissolving stoichiometric amounts of tetraiodoterephthaloyl chloride, one of ethylene diamine and an analog of ethylene diamine, and trimethylamine (TEA) into N-Methyl-2-pyrrolidone (NMP) in a dried Schlenk flask under argon atmosphere, wherein the analogs include hexamethylenediamine and other aliphatic, cycloaliphatic, and aromatic diamines; stirring the Schlenk flask overnight at room temperature; diluting the mixture with water forming a slurry; collecting the slurry as a light yellow solid by vacuum filtration; washing the solid with ethanol and diethyl ether; and crushing the solid and drying it using a high vacuum to give at least one of the polymer or trimer in quantitative yield. 11. The process according to claim 10, wherein polymer-metal composites are prepared by trapping micron particles of aluminum within the polymer matrix of one of the polymer or trimer during the polymerization reaction. 12. The process according to claim 11, wherein the polymer-metal composites are coated with an evaporative layer of perfluoro compound. 13.
