Abstract

The Landau-de Gennes free energy expansion coefficients for nematic polymers are evaluated on the basis of a molecular-statistical model. It is proved that the obtained expansion provides a reliable qualitative description of the phase transition to the nematic state for polymers with arbitrary molecular length and rigidity. It is demonstrated that this transition is always of the first-order type and the jump of the order parameter is weakly dependent on the molecular length and rigidity.
