Hansen solubility parameters were developed by Charles M. Hansen in his Ph.D thesis in 1967 [1] [2] as a way of predicting if one material will dissolve in another and form a solution. [3] They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way.
(However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2, and ethanol is likely to be the best solvent of those tabulated. However, the latter is polar ...
His 1967 doctoral thesis (Dr. techn.) [3] provided the basis for what came to be called Hansen solubility parameters, or HSPs. [4] In addition to providing a theoretical framework, the thesis provided the first working set of HSP values for common solvents and for a range of commercial polymers, making it of immediate practical use to academia ...
Solubility parameter may refer to parameters of solubility: Hildebrand solubility parameter, a numerical estimate of the degree of interaction between materials, and can be a good indication of solubility; Hansen solubility parameters, developed by Charles Hansen as a way of predicting if one material will dissolve in another and form a solution
The Hansen solubility parameter (HSP) values [14] [15] are based on dispersion bonds (δD), polar bonds (δP) and hydrogen bonds (δH). These contain information about the inter-molecular interactions with other solvents and also with polymers, pigments, nanoparticles, etc. This allows for rational formulations knowing, for example, that there ...
The Flory–Huggins solution theory is a theoretical model describing the solubility of polymers. The Hansen solubility parameters and the Hildebrand solubility parameters are empirical methods for the prediction of solubility.

Some of the Hansen solubility parameter data is not in agreement with original sources. The example with finding substitute mixtures for chloroform is not valid with the current values of the parameters of dioxane. Hansen's book has the values 19.0,1.8,7.4 for the three parameters D,P,H.
