Conclusions
-
1.
The stability of PEE depends on the degree of esterification; with increasing concentration of unesterified hydroxyl groups, the stability of the ester decreases.
-
2.
The oxidation of PEE by oxygen at 200°C is accompanied by thermal-oxidative breakdown with the formation of alcohols and acids.
