Abstract
The experimental study of polymer degradation processes in a solution is carried out. A mathematical description of the time dependences of the main polymer structural characteristics, i.e., the number average Mw and the weight average Mn molecular weight and the polydispersity coefficient Kp are obtained. For the model adequacy to be tested and the calculation error to be estimated, linear polymers—SKD-ND rubbers— are used as experimental samples. The change in the polymer molecular weight distribution (MWD) and its parameters are studied by gel permeation chromatography. The resulting dependences can be used for the process control systems. The developed mathematical description relates the controllable and control parameters in the structure (initial reagent concentrations, the reagent ratio, reaction temperature, etc.). However, the complete reconstruction of the mode of the MWD and its time dependence cannot be achieved.
