    Abstract

    The contribution of rigidity to bending of the macromolecules to the elastic energy of a nematic polymer has been studied. All the 3 corresponding elasticity coefficients have been found for a model with point interaction between the short parts of the polymer chains. The ratio of these coefficients depends strongly on the chain length (in the effective segments) and on the rigidity distribution along the macromolecular contour. For long persistent molecules, the modulus of elasticity in cross-wise flexing is very high, whilst for the rods and freely-jointed chains this modulus is fairly high for longitudinal flexing.
