Problems solved by technology

In order to realize lyotropic liquid crystal polymers, it is necessary to use rigid rod-shaped polymers, but usually the solubility of rigid rod-shaped polymers in water or organic solvents is difficult, and it is necessary to use corrosive solvents such as sulfuric acid, or dissolve them at high boiling points at high temperatures. in polar solvents

Synthetic example 1

[0254] (1) Synthesis of polymer

[0255] Put diamine (DA-1) (1.88g, 10.0mmol), m-cresol (30mL) and triethylamine (2.43g, 24.0mmol) in a three-necked flask equipped with a reflux tube, a thermometer, and a nitrogen gas introduction tube. Stirring was carried out at 80°C under nitrogen. After dissolving diamine, acid dianhydride (TA-1) (2.09g, 9.6mmol) and benzoic acid (1.71g, 14.0mmol) were added, and after stirring at 80 degreeC for 3 hours, it stirred at 180 degreeC for 12 hours. Accompanied by the imide ring-closing reaction, the polymer gradually precipitated, and the reaction mixture changed from a black-yellow solution to an orange-red slurry. After the reaction was completed, the reaction mixture was left to cool, and poured into acetone to solidify. The obtained coagulum was filtered, stirred and washed in acetone, then stirred and washed in isopropanol, and vacuum-dried at 120° C., thereby obtaining the repeating unit constituting the polymer comprising the following...

[0271] (1) Preparation of the composition

[0272] The polymer (PI-1) obtained in Synthesis Example 1 was dissolved in water, and ion-exchanged by a strongly acidic cation-exchange resin, thereby obtaining a pair of cations from Et 3 NH + was replaced by H + Aqueous solution of acidic polymer (hereinafter referred to as "acidic polymer (PI-1A")). Dialysis tube made of regenerated cellulose (cut-off molecular weight 3500, manufactured by Spectra / Por) The obtained aqueous solution was dialyzed at room temperature against distilled water to further refine it. After the dialyzed aqueous solution was concentrated under reduced pressure, an acidic functional group was added to the acidic polymer (PI-1A) to obtain 1 molar equivalent of the basic monomer (M-1), then add the polymerization initiator (I-1) and dissolve it. By using a filter with a pore size of 0.45 μm, the obtained aqueous solution is filtered to prepare an acidic polymer (PI-1A) and the composition (C-1) in which th...

Description

[0001] Cross-reference of related applications [0002] This application is based on Japanese Patent Application No. 2018-230868 for which it applied on December 10, 2018, and uses the description content here. technical field [0003] The present disclosure relates to a composition and its use. Background technique [0004] The lyotropic liquid crystalline polymer has an isotropic phase in which the arrangement of molecular chains is random when the critical concentration is less than the critical concentration, but becomes a liquid crystal phase when the critical concentration is greater than the critical concentration. In the liquid crystal phase, it becomes an aggregate of minute domains in which molecular chains are aligned in one direction, and exhibits optical anisotropy. Furthermore, when the solution of the liquid crystal phase undergoes shear deformation, the molecular chains are oriented along the flow direction. In order to realize lyotropic liquid crystal poly...
