Abstract

This study presents a comprehensive analysis of the carbammonolysis reaction of polyvinyl alcohol, combining experimental investigation with thermodynamic modeling. The aim is to determine optimal conditions for the synthesis of polyvinylamide water-soluble polymers exhibiting pronounced surface-active properties. Based on experimental data, key parameters affecting conversion efficiency and structural characteristics of the product were identified. Thermodynamic analysis provided insight into the energetic profile and reaction mechanism. The obtained results contribute significantly to the field of targeted synthesis of functional polymers and can be applied to scale-up and optimization of industrial processes for producing water-soluble polymer compositions with tailored properties.
