Abstract
Poly(ethylene oxide) (poly(oxy-1,2-ethanediyl) is rapidly oxidized by hydroxyl (HO.) and hydroperoxyl (HO2.) radicals generated by photolysi s of hydrogen peroxide (H2O2) or by the catalytic decomposition of H2O 2 by metallic silver. This process is accompanied by a chain scission during which the molecular weight decreases and the polydispersity cha nges. As a result of this process, the crystalline structure of poly(e thylene oxide) disappears, and the polymer becomes completely amorphou s. (C) 1995 John Wiley and Sons, Inc.
