  • What is the hydrolysis of polyamides?
  • Abstract The hydrolysis of polyamides has been studied in buffered acid solution at 110°C. at an amide concentration of 0.05 M. In the case of polyacrylamide, the reaction was carried out in acetat...

  • What is the hydrolysis of acrylamide-acrylic acid copolymers?
  • Compagnie Franise des Pdtroles, Centre de Recherche de Beauplan, Route de Versailles, 78470 St-Remy les Cheweuse, France (Received 26 June 1987; accepted 5 November 1987) The hydrolysis of acrylamide-acrylic acid copolymers has been studied as a function of pH and of the initial composition of the samples.
  • Is there intramolecular catalysis of polyacrylamide and acrylamide-acrylic acid copolymers?
  • CONCLUSIONS We have carried out some experimental investigations of hydrolysis of polyacrylamide and acrylamide-acrylic acid copolymers over a range of pH where the mechanism has not already been elucidated. Our results confirm the existence of intramolecular catalysis by undissociated neighbouring carboxylate groups at low pH.
  • What is the acceleration effect of polyacrylamide hydrolysis?
  • (ii) Constant pH. In Figure 14 some predictions of hydrolysis kinetics of polyacrylamide are given for different constant pH and three values of Z. These simulations correspond to a polymer concentration of 8 x 10-4gcm-3 and T= 80. The acceleration effect is significant for pH up to 7 and becomes negligible for higher pH.
