5. Thermal stability of the SAP-AP systems

Thermal degradation of polymer leads to chemical changes of the polymer structure. For instance, in the case of polymers derived from polyacrylamides, high temperatures induce the hydrolyzation of the acrylamide group to the acrylate moiety. These hydrolysis reactions are strongly correlated to temperature; thus, the higher the temperature, the higher the hydrolysis [2]. In this study, both short- and long-term thermal stabilities of the AP polymers and the corresponding SAP-AP systems were evaluated.
