- Can TGA technique be used on polyacrylamide-type polymer?
- Concerning the use of TGA technique on polyacrylamide-type polymer, the research work published to date has focused on investigating changes of polymer’s thermal stability as a result of successful modification of polymer structure incorporated with different monomer units , , .
- Which polymers were selected for a polyacrylamide test program?
- Chemicals. 9 commercial polyacrylamide samples including N-Vinylpyrrolidone (NVP) containing polymers, sulfonated polymers, sterically modified polymers and an hydrophobically associating polymer were selected for test program. The polymer information including names, types and vendors are listed in Table 2. Table 2. Polymer information. 2.2.
- Does TGA measure long-term stability of polymers in presence of impurities?
- One of objectives of this study is to establish the correlation between TGA measurement and long-term stability of the polymers in the presence of the impurities. It is of practical importance for applications. Coats-Redfern’s model was introduced to determine kinetic parameters of polymers from TGA data.
- Do polyacrylamide-type polymers have good thermal stability?
- Polyacrylamide-type polymers with good thermal stability present good long-term stability at high temperature and high salinity conditions. Viscosity reduction of polyacrylamide-type polymers with good thermal stability was owing to polymer main chain degradation at harsh conditions.
