Thermotropic Liquid-Crystal Polymers with Mesogenic Groups in the Main Chain,sized the potential capacity to form a liquid-crystalline phase for such chains based on qualitative considerations. Such polymers were independently synthesized and characterized as LC by Roviello and Sirigu . They departed from almost the same qualitative considerations, and assigned the functi

Liquid-Crystal Polymers of the Cholesteric Type,ial state of solutions of poly-?-benzyl-L-glutamate (PBG-L), which forms a lyotropic mesophase in certain so-called coiling solvents . These highly anisotropic solutions and the PBG-L films prepared from them exhibited elevated optical activity (the specific optical rotation attained 800%nm

Rheological Properties of Liquid-Crystal Polymers,es and consequently convert an isotropic system into an anisotropic system. Of course, not any induced anisotropy can be identified with the LC state (this problem will be especially discussed), but it is possible to partially agree with Cogswell on this question : “Liquid crystallinity is a rheo

Conclusion,ro-molecular systems of different classes. Despite the fact that both linear and branched polymers which differ in chemical structure, chain rigidity, stereo-regularity, the capacity for crystallization, etc. are included in the class of liquid-crystal polymers, there is also a common cause giving r
