Embodiment 1

[0165] In a four-necked separable flask equipped with a stirring device, measure 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane (18.6g, 60.0mmol), 4, 6-Dichloropyrimidine (8.9g, 60.0mmol) and potassium carbonate (11.1g, 81.0mmol), and N-methyl-2-pyrrolidone (64g) were added, and reacted at 130°C for 6 hours under a nitrogen environment. After completion of the reaction, N-methyl-2-pyrrolidone (368 g) was added for dilution, and after removing the salt by filtration, this solution was poured into methanol (9.1 kg). The precipitated solid was filtered out, cleaned with a small amount of methanol, filtered out again and recovered, and then dried at 120° C. for 12 hours using a vacuum drier under reduced pressure to obtain the polymer of Example 1 represented by the following formula (10) (yield 20.5 g, 90% yield). of the resulting polymer 1 H-NMR spectrum is shown in figure 1 .

Embodiment 2

[0168]In a four-necked separable flask equipped with a stirring device, measure 1,1-bis(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane (9.3g, 30.0mmol), 4- tert-butylcatechol (5.0g, 30.0mmol), 4,6-dichloropyrimidine (8.9g, 60.0mmol) and potassium carbonate (11.2g, 81.0mmol), and N-methyl-2-pyrrolidone (109g ) and toluene (46 g) were stirred. Under a nitrogen atmosphere, toluene was refluxed at 100° C. for 2 hours, toluene was distilled off, and the reaction was further carried out at 130° C. for 6 hours. After completion of the reaction, N-methyl-2-pyrrolidone (249 g) was added for dilution, and after removing the salt by filtration, this solution was poured into methanol (7.5 kg). The precipitated solid was filtered out, washed with a small amount of methanol, filtered out again and recovered, and then dried at 120° C. for 12 hours using a vacuum drier under reduced pressure to obtain the polymer of Example 2 represented by the following formula (11) (yield 8.8 g, yield 46.7%)...

Embodiment 3

[0171] In a four-necked separable flask equipped with a stirring device, measure 2-tert-butylhydroquinone (5.8g, 35.0mmol), 2,5-di-tert-butylhydroquinone (7.8g, 35.0mmol ), 2,2-bis(4-hydroxyphenyl)propane (6.8g, 30.0mmol), 4,6-dichloropyrimidine (14.9g, 100.0mmol) and potassium carbonate (18.7g, 135.0mmol), and added N-methyl-2-pyrrolidone (102.9 g) was reacted at 130° C. for 6 hours under a nitrogen atmosphere. After completion of the reaction, N-methyl-2-pyrrolidone (300 g) was added for dilution, and after removing the salt by filtration, this solution was poured into methanol (6 kg). The precipitated solid was filtered out, cleaned with a small amount of methanol, filtered out again and recovered, dried at 120° C. for 12 hours using a vacuum drier under reduced pressure to obtain the polymer of Example 3 represented by the following formula (12) (yield 23.4 g, 83.5% yield).

Description

technical field [0001] The present invention relates to a polymer, a resin composition and a resin molded article. Background technique [0002] Polymers formed by the copolymerization of dihydric phenolic monomers and aromatic dicarboxylic acid monomers are widely used in electrical, automotive, and mechanical fields due to their high heat resistance and transparency. Generally, in these fields, after dissolving the above-mentioned polymer in a solvent to prepare a resin composition, a resin molded article such as a film is formed from the resin composition and used for various applications. [0003] For example, in Japanese Patent Application Laid-Open No. 8-269214, for polyarylenes obtained by copolymerizing bisphenol A as a dihydric phenolic monomer and terephthalic acid and isophthalic acid as an aromatic dicarboxylic acid monomer, The ester was dissolved in methylene chloride to prepare a resin composition, and a film was formed from the resin composition.
