Hydrolysis of polyacrylamide and acrylic acid-acrylamide

The hydrolysis of acrylamide-acrylic acid copolymers has been studied as a function of pH and of the initial composition of the samples. Our experimental results confirm the intramolecular catalysis by neighbouring undissociated carboxylate groups for 3 < pH < 5, as already demonstrated by Smets et al., and the catalysis of OH − ions with autoretarded kinetics for pH > 11.
