  • 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 , , .
  • Why do acrylamide polymers vary in TGA/DTA values?
  • The method of synthesis, molecular mass and the possible interaction of polyacrylamide with other components are some factors which may be responsible for the variance of experimentally determined T g values of the acrylamide polymer . TGA/DTA curves of a Aam hydrogel, and b TGA/DTA curves of Aam/NaCMC and, c Aam/NaCMC/MgO hydrogel
  • How are polyacrylamide-based hydrogels obtained?
  • Polyacrylamide-based hydrogels were obtained by chemical crosslinking of MBA using acrylamide, sodium carboxymethylecellulose (NaCMC), N,N,N ′, N ′-tetramethylethylenediamine (TEMED) and ammonium persulfate (APS) as the initiators.
  • Can thermogravimetric analysis predict long-term stability of polyacrylamide-type polymers?
  • This study aims to apply thermogravimetric analysis technology to develop a facile way for long-term stability prediction of polyacrylamide-type polymers at high temperature and high salinity reservoir conditions, to maintain sufficient viscosity in chemical flooding.
