“…Solvent fractionation can be used to selectively dissolve a subset of lignin, decreasing the molecular mass polydispersity and targeting its molecular features to a specific application. [4][5][6] As the interactions between lignin and solvent depend sensitively on the solvent at hand, changing the solvent results in the dissolution of fractions with different properties. 7 Using a solvent blend, these solvent-lignin interactions can be tuned gradually by altering the solvent composition.…”

“…Many polymers have a large diversity of their chemical structure and chain lengths, [ 53 ] drastically increasing the number of components. Despite its reported large affect, [ 54 ] this variety is often not included in theoretical studies. The demonstrated procedure in the presented relatively simple conceptual examples can be applied in the same manner for more components, providing options for theoretical many‐component studies.…”

The rational development of sustainable polymeric materials demands tunable properties using mixtures of polymers with chemical variations. At the same time, the sheer number of potential variations and combinations makes experimentally or numerically studying every new mixture impractical. A direct predictive tool quantifying how material properties change when molecular features change provides a less time‐ and resource‐consuming route to optimization. Numerically solving Flory–Huggins theory provides such a tool for mono‐disperse mixtures with a limited number of components, but for multi‐component systems the large number of equations makes numerical computations challenging. Approximate solutions to Flory–Huggins theory relating miscibility and solubility to molecular features are presented. The set of approximate relations show a wider range of accuracy compared to existing approximations. The combination of the analytical, lower‐order, and more accurate higher‐order approximations together contribute to a broader applicability and extensibility of Flory–Huggins theory.

“…Other methods such as gel permeation chromatography (GPC) (Altgelt, Moore 1967;Minor 1979) and counter-current distribution (Cantow 1967) can also be used for the fractionation of cellulose (Krässig 1971;Valtasaari, Saarela 1975).…”
