Sorption of liquids in polymers is an important factor for any application where polymers come into contact with an organic solvent. We report on sorption properties of hydrophobic poly(ethylene chlorotrifluoroethylene) Halar®901 in view of its potential application as a dense or porous membrane material. For the first time, the liquid phase sorption of 34 common organic liquids such as linear C6-C10 alkanes, methyl-, ethyl- and propyl-derivatives of benzene and cyclohexane, and of linear-, branched- and cyclic- ethers, ketones, acetates and chloro-derivatives in the 1:1 alternating copolymer of ethylene and chlorotrifluoroethylene (ECTFE) is presented. The correlation between the solvent molecular structure, its physico-chemical properties and the total mass uptake are discussed in detail. Furthermore, two sorption-predictive methods developed from
experimental data allow to anticipate the behavior of solvents in Halar®901 based exclusively on three types of structural units (C-bone, functional groups, molecular geometry) or four (molar mass, surface tension, boiling temperature and Van der Waals volume) parameters only. A successful verification of our methods proved their versatility in predicting organic liquid sorption in ECTFE material Halar®901.
