A Simple Method for Estimating the Solubility Parameter of Small Molecules and Polymeric Materials

Abstract

Abstract The study relates to the problem of selecting a solvent for organic polymers during their chemical processing. Based on the method of Askadsky, simple schemes were proposed for calculating the solubility parameter of small molecules and polymeric materials using the structural elements of molecules. On the example of small molecules and polymers it was shown that the constructed methods are not inferior in accuracy to methods of Askadsky, Small, and Van Krevelen. The proposed schemes make it possible to calculate the solubility parameter and find acceptable solvents for a polymer material with a known value of the solubility parameter. The schemes were tested on specific examples and the possibility of their application for the selection of a solvent was demonstrated.
