Rheokinetics of synthesis of polysulphone in concentrated solutions

Abstract The effect of temperature and solution concentration on the rheokinetics of formation of polysulphone in solutions of various concentrations is studied. For concentrations of polymer > 60 wt.% the reaction is retarded as a result of diffusional limitations. The transition into the diffusion-controlled region is described by a complex parameter, i.e. the product of the solution viscosity and the degree of polymerization.
