Abstract
A mean field theory for cholesteric polymers based on the elastic mode l is presented. The effect of flexibility and the biaxial order and ne matic order parameters arc studied. The biaxial order and nematic orde r parameters are increasing functions of chirality and vary slightly w ith flexibility. Biaxiality is shown to be important for the transitio n temperature and the cholesteric pitch as well as the latent heat of transition.
