HnV is a group contribution method, where every single group in the chemical structure contributes towards the SPs of the compound. The δd, δp, δh, δT and molar volume V were calculated by using equation 1 to 6 (Table and Table -S24). Expectedly, and as reported for a library of 18 different triblock copolymers , the HnV could not differentiate between the structural isomers i.e. pBuOx/pPrOzi and pPentOx/pBuOzi resulting in same δd, δp, δh, δT (Figure , Table ) and molar volume values (Figure ). Generally, with the exception of δd value, the δp, δh and δT values of hydrophilic pMeOx remained significantly higher in comparison to all four hydrophobic blocks (Figure ). Overall, the SPs values for all the hydrophobic blocks by HnV method remained in close range. Interestingly, the YMB method was able to differentiate between the structural isomers with respect to δd, δp, δh values.
