摘要: A method of rheokinetic analysis is applied to free-radical polymerization acrylamide in a water solution initiated by an oxidizing reducing system. The special feature this system the second-order kinetics initiation stage. Theoretical predicts main effects, such as time dependence viscosity and degree polymerization, concentration influence monomer initiator, temperature profile at different experimental conditions. Experimental data confirmed idea about reaction initiation. Observed dependencies were close theoretical predictions. Rate constants individual stages “apparent” values activation energy found compared with published values. possibility solving inverse problem from viscometric was confirmed.
