Adhesive liquid‐crystalline polymers
Macromolecular Symposia, 1998AbstractThe synthesis and characterization of liquid‐crystalline polymers with possible good adhesive properties is reported. These polymers are prepared by alternating copolymerization of maleic anhydride and mesogenic alkenes. The spacer length m is varied (m = 2, 3, 4, 6, 8 and 9) and methoxybiphenyl is used as the mesogenic group.

Liquid-liquid phase equilibria in polymer solutions and polymer mixtures
Macromolecular Symposia, 2002The pressure dependence of liquid-liquid equilibria in weakly interacting binary macromolecular systems (homopolymer solutions and blends) will be discussed. The common origin of the separate high-temperature/low-temperature and high-pressure/low-pressure branches of demixing curves will be demonstrated by extending the study into the region of ...

Phase Behaviour of Polymer-Liquid Crystal and Polymer-Polymer Blends
Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 2001DSC and optical microscopy were used to study the phase behavior of blends of two members of a group of side-chain cholesteric liq. cryst. silicones. One of these siloxane-based polymers forms a single blue phase. The exptl. phase diagram is constructed and then compared to the case in which one of the polymers is replaced by a chiral nematic liq ...

Polymer Dispersed Liquid Crystals
2019Low molar mass liquid crystals (LCs) are typically not soluble in polymer systems to any great degree. When the two different materials are mixed, this leads to two-phase systems whose morphology depends on a variety of factors including, primarily, the concentration.

Liquid Crystal Polymer Membranes
2015Liquid crystals (LCs) combine properties of both liquids and crystals and can be organized in a variety of nanostructured polymer films with a monolithic structure. Therefore, polymer-based LCs are ultimately suited as membrane with an accurately controlled nanoporosity.

Photorefractive polymer-dispersed liquid crystals
Optics Letters, 1997We report observation of the photorefractive effect in functionalized polymer-dispersed liquid crystals. The photoconductive properties are provided by the polymer matrix, and the field-dependent refractive-index changes are generated by the dispersed nematic liquid-crystal droplets.

Abstract A new series of poly(arylidene-ether)s containing cyclopentanone was synthesized by polycondensation of 4,4′-diformyl-α,ω-diphenoxyalkane 1 – 4 and 4,4′-diformyl-2,2′-dimethoxy-α,ω-diphenoxyalkane 5 – 8 with cyclopentanone. The inherent viscosity of the polymers were in the range of 0.38–1.23 dl/g.
