Popis:	1. Studies of the kinetics of radical polymerization of DAC in aqueous solutions in conditions of deep degrees of conversion of monomer into polymer with a combination of dilatometric, calorimetric, and PMR spectral methods showed that in the conditions selected, poly-merization is accompanied by autoacceleration whose onset corresponds to certain values of the concentration of the polymer formed and is in all probability due to the formation of a fluctuation linkage network of the polymer in the reaction solution. 2. The quantitative dependence of the values of the characteristic concentrations of the polymer corresponding to the onset of autoacceleration on the degree of polymerization of the polymer formed at the onset of autoacceleration was established.
