摘要

The analysis of polymer molecular-weight characteristics formation mechanism in the process of styrene polymerization initiated by benzoylperoxide, tert,-butylperbenzoate and dicumylperoxide during gel effect was carried out. It was shown that the reaction kinetics parameters ratio, which describes macroradicals temination, and their changes with monomer conversion are dominant in the prediction of polymer molecular weight. it can't be prognosticated only from starting conditions and the general rate of process of different stages.
