Abstract: We extend our molecular mean field model of highly polar compounds to include hard rod interactions to develop a hybrid model. The latter interactions are restricted to second virial terms, following a method developed by Koda and Kimura. This allows us to calculate pressure-temperature phase diagrams. Depending on the model parameters used, the phase diagrams exhibit the following features: nematic-nematic phase transition, bounded SmAd region, double reentrance, reentrant nematic lake surrounded by the smectic A phase (the reentrant nematic lake merging with the main nematic sea) as well as the possibility of quadruple reentrance. We compare the calculated phase diagrams with the available experimental data.
