A new method is presented for modeling and controlling polymer molecular weight distribution (MWD) and tensile strength in a batch suspension polymerization of styrene. The molecular weight distribution is modeled by computing the weight fraction of the polymer in different chain length intervals. T

Free-radical polymerization of styrene was carried out in the presence of chain transfer agents (CTAs) with functionality, f Ο 1-4. The size exclusion chromatography (SEC) with an ultraviolet absorption detector (UV) was used to measure the molecular weight distribution (MWD). A Monte Carlo simulati
The polymerization reactivity of isobutylene/SnCl 4 mixtures in the absence of polar solvent, was investigated in a temperature interval from Οͺ78 to 60 Β°C. The mixture is nonreactive below Οͺ20 Β°C but slow polymerization proceeds from Οͺ20 to 20 Β°C with the initial rate r 0 of the order 10 Οͺ5 mol β l
