WebThis will give an equation, known as the Flory–Fox equation (Fox and Loshaek, 1955), of the form: (4.1) T g = T g ∞ − ( K M ¯ n ) where T g ∞ is the glass transition temperature … 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. The theory was initially conceptualized by Paul Flory in 1941 and …
