  • Properties of Polyacrylamides

    2020-7-11 · Polyacylamides are high molecular weight water soluble or swellable polymers formed from acrylamide or its derivatives. Their glass transition temperature is well above room temperature (> 400 K). The only commercially important polyacrylamide is poly(2-propenamide) which is simply called polyacrylamide or PAM [-CH 2 CH(CONH …

  • Solubility of Polyacrylamide in Supercritical

    2016-11-9 · The solubility data of PAM in SCCO2 was correlated with five density-based semiempirical models (Chrastil, A-L, M-T, S-S, and Bartle) and A-L model obtained the best correlated results for PAM with different molecular weight. The self-consistency of PAM solubility was verified by M-T model.
