Abstract
The kinetics of copolymerization of sodium 2-acrylamido-2-methylpropanesulfonate with N-vinyl-pyrrolidone in aqueous solutions in the presence of potassium persulfate at 40 – 70°C and the molecular characteristics of the resulting complexes were studied, as influenced by the total concentration of the initial monomer mixture, comonomer ratio, temperature, and conversion. The kinetic data were explained taking into account the state of the ionic groups, electrostatic interactions between the reacting particles, and complexation of comonomers in the course of copolymerization.
