[0297] [Preparation of polymer composition]
[0298] The polymer composition used in the present invention is preferably prepared in the form of a coating liquid so as to be suitable for forming a liquid crystal aligning film. That is, the polymer composition used in the present invention is preferably prepared in the form of a solution in which a resin component for forming a resin coating is dissolved in an organic solvent. Here, the resin component refers to a resin component containing the above-mentioned photosensitive side chain type polymer capable of expressing liquid crystallinity. In this case, the content of the resin component is preferably 1% by mass to 20% by mass, more preferably 3% by mass to 15% by mass, particularly preferably 3% by mass to 10% by mass.
[0299] In the polymer composition of this embodiment, the above-mentioned resin components may all be the above-mentioned photosensitive side-chain polymers capable of exhibiting liquid crystallinity,...
Embodiment
[0410] The methacrylic monomers MA1 and MA2 and the additives T1 and T2 used in Examples are shown below.
[0411] In addition, MA1 and M2 were respectively synthesized as follows. That is, MA1 was synthesized by the synthesis method described in the patent document (WO2011-084546). MA2 was synthesized by the synthesis method described in the patent document (Japanese Patent Laid-Open No. 9-118717).
[0412] Additives T1 (3-aminomethylpyridine) and T2 (1-(3-aminopropyl)imidazole) used commercially available additives.
[0413]
[0414] In addition, the abbreviations of the reagents used in this example are shown below.
[0415] (Organic solvents)
[0416] THF: Tetrahydrofuran.
[0417] NMP: N-methyl-2-pyrrolidone.
[0418] BC: butyl cellosolve.
[0419] (polymerization initiator)
[0420] AIBN: 2,2'-azobisisobutyronitrile.
Synthetic example 1
[0422] MA1 (4.99 g, 15.0 mmol) and MA2 (4.60 g, 15.0 mmol) were dissolved in THF (88.5 g), and after degassing with a diaphragm pump, AIBN (0.246 g, 1.5 mmol) was added and degassed again. Then, it was made to react at 50 degreeC for 30 hours, and the polymer solution of the methacrylate was obtained. This polymer solution was added dropwise to diethyl ether (1000 ml), and the resulting precipitate was filtered. This deposit was wash|cleaned with diethyl ether, and it dried under reduced pressure in 40 degreeC oven, and obtained the methacrylate polymer powder.
[0423] NMP (54.0g) was added to the obtained methacrylate polymer powder (6.0g), and it stirred and melt|dissolved at room temperature for 5 hours. BC (40.0g) was added and stirred to this solution, and the methacrylic polymer solution B1 was obtained.
