Notes:
The thermodynamics of the binary system oligo(ethylene glycol) (OEG) - oligo(propylene glycol) (OPG) is investigated by lightscattering. The Flory-Huggins interaction parameter χ12 for this system is determined by the decrease of the OEG melting point in a mixture with OPG. At 310,8 K the system is compatible in the concentration range between 0 and 30 vol.-% of OPG in the mixture. The analysis of the temperature dependence of χ12 according to the novel Flory theory leads to the assumption that mixing in this system occurs at a lower critical mixing temperature.
