Molecular Dynamics In Some Side Chain Liquid Crystalline Polymers

We give an introduction to the method of dielectric spectroscopy to study molecular motions on side chain liquid crystalline polymers. The principal relations between the dielectric permittivity and the microscopic dynamics for low molecular liquid crystals and their modifications due to polymer properties are presented. Refering to our previous works we summarize the models for the different molecular motions in the liquid crystalline side chain polymers. We discuss the effects of structural changes for some examples. At last we outline some aspects for potential applications, that result from our investigations.
