Embodiment 1

[0042] Embodiment 1: A synthetic method

[0043] Add 4g of bisphenol A, 6.88g of bisphenol A bissulfonyl fluoride, 25ml of sulfolane, and 5.32g of potassium carbonate into a reaction bottle with a high-efficiency stirrer at one time, and react at 170°C for 4 hours; once in another reaction bottle Add 4g of bisphenol A, 4.86g of 1,5-dichloroanthraquinone, 5.32g of potassium carbonate, and 25ml of sulfolane, and react at 170°C for 4 hours, then combine the two systems together and continue to react for 4 to 10 hours. Pour into water for precipitation to obtain the final block polysulfate, Mn=31018g / mol, Tg=151.4°C.

[0044] Embodiment 2: A synthetic method

[0045] Add 4g of bisphenol A, 7.56g of bisphenol A bissulfonyl fluoride, 25ml of sulfolane, and 5.32g of potassium carbonate into a reaction bottle with a high-efficiency stirrer at one time, and react at 170°C for 4 hours; Add 4.4g of bisphenol A, 4.86g of 1,5-dichloroanthraquinone, 5.32g of potassium carbonate, and 25ml of sulfolane, and react at 170°C for 4 hours, then combine the two systems together and continue the reaction for 4 to 10 hours. Pour into water for precipitation to obtain the final block polysulfate, Mn=19873g / mol, Tg=145.1°C.

Embodiment 3

[0046] Embodiment 3: A synthetic method

[0047] Add 4.56g of bisphenol A, 9.8g of bisphenol A bissulfonyl fluoride, 34ml of sulfolane, and 6.08g of potassium carbonate into a reaction flask with a high-efficiency stirrer at one time, and react at 170°C for 4 hours; Add 5.7g bisphenol A, 5.54g 1,5-dichloroanthraquinone, 6.08g potassium carbonate, 34ml sulfolane, react at 170°C for 4 hours, then combine the two systems together and continue the reaction for 4-10 hours. The system was poured into water for precipitation to obtain the final block polysulfate, Mn=25219g / mol, Tg=131.8°C.

Abstract

The invention discloses high-temperature-resistant block polysulfate. An anthraquinone group, a fluorenyl group and a phenolphthalein Cardo group with good thermal stability are introduced on the basis of an original polysulfate structure to obtain at least one of structural formulas I, II and III, so that the heat resistance of the polysulfate is improved. The invention further discloses a preparation method of the high-temperature-resistant block polysulfate, and the novel high-temperature-resistant block polysulfate is prepared through a synthesis method A and a synthesis method B. The method provided by the invention has the advantages of simple and stable synthesis process, economy, mild preparation conditions and small environmental pollution, and the product has high glass transition temperature, good mechanical properties and the like, and has wide application prospects in the fields of aviation, communication, electronics and microelectronics.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, and in particular relates to a high-temperature-resistant block polysulfate and a preparation method thereof. Background technique [0002] Due to its excellent performance, polyester materials are widely used in chemical fiber, packaging, electronic appliances, medical and health care, construction, automobiles and other fields; in the context of continuous growth in global polyester consumption, China's polyester production capacity has increased significantly growth, but none of the polyester materials is original in China, and many high-end materials are still mainly imported; in this context, a new type of polyester material with China's independent intellectual property rights—polysulfate (PSE) was born. [0003] Compared with traditional polycarbonate (PC), polysulfate has better aging resistance, excellent acid and alkali resistance, solvent resistance and other adva...
