“…We recognize that there are several methods to perform quantitative structure property relationship (QSPR) modeling in terms of Abraham's LSER descriptors based on inter‐relationships between the LSER molecular descriptors and partial solvation parameters (PSPs), and HSPs, wherein COSMO‐RS calculations provide the bridge that unifies the LSER, PSP, and HSP methods. The successful application of these predictive theories to a multitude of problems is well‐documented in the literature, but rather than adapting these methods to handle our P3HT‐solvent gradient systems, which is beyond the scope of this study, we chose to use experimentally measured LSER parameters to perform our analysis.…”

“…The final analysis of the PCL solvent affinities utilized the LSER molecular descriptor methodology developed by Panayiotou et al . Within this formalism, the polymer–‐solvent affinities can be defined in terms of Flory–Huggins interaction parameters, χ 12,FH , which are defined in terms of tabulated LSER descriptors V x , A , B , E , and S , lefttrueitalicφitalic2sans-serif2italicχ12,FH=10,000italicφitalic2sans-serif2italicVx,1italicRT()sans-serif3.1+italicEitalic1italicVx,1+sans-serif3.1+italicEitalic2italicVx,2sans-serif2+()S1Vitalicx,italic1+S2Vitalicx,italic2sans-serif2+[]r1νHsans-serifln()x1ν10sans-serifln()x1ν01italicmixture[]r1ν11+sans-serif2sans-serifln()sans-serif1r1ν11pure1 where the solvent and polymer are denote 1 and 2, respectively, and φ 2 is the volume fraction of the PCL polymer.

“…where x i is the mole fraction of the i th compound, and r i is the number of identical segments with a hard core volume Vi* in the i th molecule. For each solvent (1) r 1 can be approximated quite well by the equation r 1 = –0.070 + 4.778 V x , where V x is the McGowan volume . For polymers (2), r 2 is evaluated using the relation V x , i / r i = 0.21, and r in the polymer–solvent mixture is given r = X 1 r 1 + X 2 r 2 .…”
