Abstract
Liquid crystalline compound (S)-5-(2-methylbutoxy)-2-[[[4-hexyloxyphenyl]imino]methyl]-phenol (MBHOPIMP) has been
prepared and characterized. Phase transition temperatures of MBHOPIMP were determined by polarizing microscopy,
differential scanning calorimetry. The retention diagrams of octane, nonane, cyclopentane, cyclohexane, ethyl acetate, butyl
acetate, iso-butyl acetate, benzene, toluene, ethylbenzene and chlorobenzene on MBHOPIMP were plotted at temperatures
between 110 and 130 o
C by inverse gas chromatography technique. Then, specific retention volume, 0 Vg , Flory-Huggins
polymer-solvent interaction parameter, ∞
12 χ , hard-core polymer-solvent interaction parameter, ∗
12 χ and effective exchange
energy parameter, Xeff were determined..
Keywords
