Thermal degradation of poly(diethyleneglycol-bis-allyl carbonate)

The assisted thermal degradation of poly(diethyleneglycol-bis-allyl carbonate), poly-CR 39, has been investigated at 300°C, under nitrogen or argon, in the presence of the metals, Fe, Cu and Zn. The major decomposition products are carbon dioxide, ethene, propene, 1,4-dioxane, 2-propen-1-ol, 2,2′-oxydiethanol carbonate, 2,2′-oxydiethanol and 1,2-di(2′-hydroxy)ethoxy ethane. A degradation mechanism is proposed.
