Abstract: Infrared-transparent polymers, useful for LWIR and/or MWIR transparency, are disclosed. The disclosed infrared-transparent polymers are low-cost, damage-resistant, and economically scalable to commercially relevant substrate areas (1 ft2 and greater). In some disclosed infrared-transparent polymers, the carbon-free polymer backbone contains a plurality of polymer repeat units of the form




wherein R1 is selected from the group consisting of alkyls, hydroxyl, amino, urea, thiol, thioether, amino alkyls, carboxylates, metals, metal-containing groups, and deuterated forms or combinations thereof; wherein R2 is (independently from R1) selected from the group consisting of alkyls, hydroxyl, amino, urea, thiol, thioether, amino alkyls, carboxylates, metals, metal-containing groups, and deuterated forms or combinations thereof; wherein n is selected from 2 to about 10,000; and wherein the carbon-free polymer backbone is linear, cyclic, branched, or a combination thereof.
