Synthesis and Functional Properties of Liquid Crystalline Polymers.

Rheology of liquid crystalline polymers

Concepts which may be used in interpreting the complex rheology of liquid crystalline polymers are reviewed. Some of them are taken from the nematodynamics of low molecular weight liquid crystals as described by the Leslie—Ericksen theory, others are intrinsic to the viscoelasticity of ordinary polymers. Tentatively, these concepts are used to construct an explanation of the band texture which ...

Synthesis and Liquid Crystalline Properties of 4,4'-disubstituted Biphenyls

Liquid Crystalline Acrylates and Their Polymers

In previous papers (1,2) the thermotropic properties and the kinetics of the bulk polymerization of the mesomorphic monomer cholesteryl acrylate have been described. In addition to cholesteryl acrylate, the methacrylate was prepared, as well as the respective acrylic methacrylic acid ester of cholestanol. We now wish to report the properties of these monomeric esters and the results of their po...

Metallo-Responsive Liquid Crystalline Monomers and Polymers

Small molecule and polymeric liquid crystalline materials have applications in a multitude of areas, ranging from displays, optical/ electronic imaging, data storage, and stress/temperature sensing to chemical/fire resistance and artificial muscle actuation. The design of typical molecular architectures that facilitate thermotropic liquid crystalline behavior is well documented. Molecules with ...

Characterization of thermotropic liquid crystalline polymers

The characterization of thermotropic, main chain liquid crystalline polymers for the type, thermal and thermodynamic properties, order, and degree of liquid crystallinity of the anisotropic phase is described through the use of the following methods: (1) polarized light microscopy, (2) wide angle X—ray diffraction, (3) differential scanning calorimetry, (4) small angle light scattering, (5) ele...
