Abstract
AbstractEnthalpies and Gibbs energies of mixing of liquid ethylene oxide oligomers with hydroxyl and methoxy end groups in tetrachloromethane are obtained by microcalorimetry and vapour pressure measurements. In this part of the publication the thermodynamic excess quantities ΔH, ΔGE and ΔSE are fitted by power series as functions of the weight fraction. Polymer‐ and solvent‐specific as well as partial thermodynamic quantities are deduced. The qualitative explanation of the strongly end group specific mixing behaviour demonstrated by these quantities is based on the induced dipol interactions of the ethylene oxide middle segments and on the hydrogen bond interactions of the OH end groups.
