  • Which polar solvent has a polar surface tension?
  • According to Van Oss, Chaudhury, and Good (VCG) theory, the surface tension components were used to calculate the PAM solubility in five different polar solvents: water, ethylene glycol (EG), acetone, ethanol, and dimethyl formamide (DMF). It was found that PAM had a monopolar surface nature, which resulted in polymer dissolution in water.
  • What is the solubility of Pam in polar solvent systems?
  • The solubility of polyacrylamide (PAM) in binary polar solvent systems or ternary cosolvent systems is used to estimate the swelling properties of a PAM hydrogel under corresponding external conditions. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 1493–1499, 2004
  • Is polyacrylamide (PAM) solvophobic or monopolar?
  • Polyacrylamide (PAM) had a monopolar surface nature, resulting in its dissolution in water. However, it was solvophobic in the other three solvents. The solubility of PAM in water was greater than in these other solvents.
  • Does polyacrylamide swell in ethanol?
  • On the other hand, plain polyacrylamide is only slightly swelled in pure ethanol and does not swell in other nonaqueous solvents, suggesting that amide-amide interactions are too strong to be dislodged by solvents, which interact far weakly than water with the polymer chains.
