Poly(ethylene oxide) (poly(oxy‐1,2‐ethanediyl) is rapidly oxidized by hydroxyl (HO • ) and hydroperoxyl (HO ) radicals generated by photolysis of hydrogen peroxide (H 2 O 2 ) or by the catalytic decomposition of H 2 O 2 by metallic silver. This process is accompanied by a chain scission during which the molecular weight decreases and the polydispersity changes. As a result of this process, the crystalline structure of poly(ethylene oxide) disappears, and the polymer becomes completely amorphous.
