[0374] [Example 1-1] Synthesis of polymer compound [4]

[0375]

[0376]To a 1000 mL four-neck flask were added 1,3-phenylenediamine[2] (35.18 g, 0.325 mol, manufactured by Amino-Chem) and 666.3 g of dimethylacetamide (DMAc, Kanto Chemical). Co., Ltd.), after nitrogen substitution, stirring was performed so that 1, 3- phenylenediamine [2] was dissolved in DMAc. After that, it was cooled to -10°C in an ethanol-dry ice bath, and 2,4,6-trichloro-1,3,5-triazine[1] (60.0 g, 0.325 mol) was added while checking that the internal temperature did not become 0°C or higher. , manufactured by Tokyo Chemical Industry Co., Ltd.). After stirring for 30 minutes, the oil bath was set to 90 to 100°C, and the temperature of the reaction solution was raised to an internal temperature of 85°C±5°C. After stirring at an internal temperature of 85°C for 1 hour, 2-(4-aminophenyl)ethanol [3] (53.56 g, 0.456 mol, manufactured by Oakwood Corporation) was preliminarily dissolved in 107.12 g of DMAc, ...

[0378] [Example 1-2] Synthesis of polymer compound [5]

[0379]

[0380] To a 150 mL four-neck flask, 25.0 g of compound P-1 synthesized in Example 1-1, 100.0 g of THF (manufactured by Junsei Chemical Co., Ltd.), and 11.66 g of pure water were added, and after nitrogen substitution, stirring was performed to dissolve P-1. in THF. Then, it heated up to 60 degreeC of internal temperature, 12.70g of 2-isocyanatoethyl acrylates (Karenz AOI, the Showa Denko Co., Ltd. make) were added, and it stirred for 3 hours. Thereafter, the temperature was lowered to room temperature, and the reaction solution was added dropwise to a mixed solution of methanol (149 g) and ion-exchanged water (448 g) to reprecipitate. The obtained precipitate was separated by filtration and dried at 80° C. for 3 hours using a vacuum dryer to obtain 21.6 g of the target polymer compound [5] (hereinafter, referred to as P-2). The compound P-2 1 The measurement results of the H-NMR spectrum are shown in fig...

Abstract

The triazine ring-containing polymer according to the present invention is, for example, a triazine ring-containing polymer containing a repeating unit structure represented by formula (24). In the formula, R102 represents a crosslinking group;

Description

technical field [0001] The present invention relates to a triazine ring-containing polymer and a film-forming composition containing the polymer. Background technique [0002] In recent years, liquid crystal displays, organic electroluminescence (EL) elements (organic EL displays or organic EL lighting), touch panels, optical semiconductor (LED) elements, solid-state imaging elements, organic thin-film solar cells, and dye-sensitized solar cells have been developed. For electronic devices such as organic thin film transistors (TFTs), high-performance polymer materials are required. [0003] Specific properties required include 1) heat resistance, 2) transparency, 3) high refractive index, 4) high solubility, 5) low volume shrinkage, 6) high temperature and high humidity resistance, 7) high film hardness, etc. [0004] In view of this aspect, the applicant has found that polymers containing repeating units having triazine rings and aromatic rings have high refractive index,...
