WebThe results corroborate the molecular weight dependent of glass transition temperature curve for monodispersed polystyrene as predicted by the Flory-Fox equation, T g = T g,∞ - K / M n. The second goal of the experiment is to determine the weight percent proportion in each of the mixtures studied.
WebFlory–Stockmayer theory is a theory governing the cross-linking and gelation of step-growth polymers. The Flory-Stockmayer theory represents an advancement from the Carothers equation, allowing for the identification of the gel point for polymer synthesis not at stoichiometric balance.
