Stable polymer oxidant for decontamination. Final report, July 1991-September 1992

TL;DRAbstract

Treatment of a variety of polymers with ozone in oxygen was investigated as a means of forming covalently-bound peroxide groups attached to solid polymeric materials. Cellulose esters, such as cellulose acetate propionate, were found to form significant amounts of peroxide groups (greater than or equal to 1 mmol/g). These ozonized cellulose esters (XAE) were extensively tested for reactivity and sorptivity against a range of CW agent simulants, especially organosulfide mustard simulants. The oxidative reactivities of XAEs were found to exceed that of model alkyl hydroperoxides and to be comparable to alkyl hydroperoxides catalyzed by transition metal compounds. They were somewhat less reactive than peracids, but also more thermally stable. Initial efforts to formulate XAEs with transition metal complexes in order to speed reaction of mustard simulants and attack refractory organophosphorus simulants were unsuccessful. It was found that the reactive peroxide groups formed by ozonolysis
