WebChain determined that penicillin was stable only with a pH of between 5 and 8, but the process required one lower than that. By keeping the mixture at 0 °C, he could retard the breakdown process. In this form the penicillin could be drawn off by a solvent. Initially ether was used, as it was the only solvent known to dissolve penicillin.

WebFlory–Huggins theory can predict phase separation in mixtures of polymers and solvents. By equating the chemical potentials resulting from Flory–Huggins theory, the equilibrium compositions of the coexisting phases can be predicted numerically from the chain lengths and interactions of the involved molecules.

WebDe Keer et al. used a matrix-based kinetic MC framework to reveal the effects of intramolecular reactions on the variation of the chain length distribution and its averages for a network polymer formed via a step-growth mechanism, with the intention to go beyond the equation derived by Carothers , Flory [8,70,71], and Stockmayer [11,12,13]. WebThe Flory–Huggins theory plays an important role in assessing the mutual miscibility of the polymer and the plasticizer. The so-called Flory–Huggins parameter of mutual interaction is the criterion defining the miscibility of PVC with plasticizers. It allows for a quantification of the affinity of the plasticizer with the polymer.
