Abstract (English):
It was studied and realized modeling of kinetics of styrene’s radical polymerization, progressing by mechanism of connection-fragmentation in dibenzyltritiumcarbonate’s presence. Model’s adequacy is proved by comparison of calculated and experimental values of styrene’s topological structure parameters. It was realized numerical experiments by model and it was studied influence of controlling factors on molecular-mass properties of polystyrene.
