No new chemical compounds were found in the copolymer acrylamide – acrylonitrile – sodium 2-acrylamido-2-methylpropanesulfonate with the composition of [72]:[10]:[18] that was subjected to thermohydrolysis at temperatures up to 160 °C, with the exception of carboxyl groups in place of amides. Thermohydrolysis up to 200 °C causes partial degradation and changes in the acrylate copolymer. The intrinsic viscosity, molecular weight and average sizes of the solvated copolymer macromolecular coils were found to decrease with increasing hydrothermal treatment temperature.
