Flory equation
WebFlory-Rehner Theory . describes the thermodynamics of swelling of polymer networks, such as vulcanized rubber. It is a simple mean-field lattice model. The Flory-Rehner equation can be used to predict the solvent uptake of crosslinked polymers as a function of crosslink density and composition. Read More Web• Flory equation-of-state and Sanchez lattice fluid theories • LCST behavior is characteristic of exothermic mixing (which could arise from specific chemical interactions) and negative excess entropy (which arises due to densification of the polymers on mixing). Neither one of these phenomena is included in the Flory-Huggins theory.

WebConventionally, Equations –(4) are used to numerically find the dependency of the binodal on M and χ. Especially for systems with many components, the process of solving Flory–Huggins equations requires appropriate initial guesses for the concentrations, and is further complicated by the larger number of variables. WebThe comparison shows that the results from the MC simulations based on Equation agree with the Flory-Stockmayer theory, while those based on Equation do not. It indicates that Equation ( 18 ) is consistent with the assumption made by the Flory-Stockmayer theory, i.e., all the active functional groups have the same probability to react with ...
