Embodiment 1

[0030] Add 1,1,3,3-tetramethyldihydrodisiloxane (6.7g, 0.05mol) and eugenol (16.4g, 0.1mol) in a nitrogen-protected container, and add toluene (92mL) to the system As a solvent, heat up to 65°C, add 3~5 drops of chloroplatinic acid solution, react at constant temperature for 6~12 hours, then cool down to room temperature, add the reaction mixture into a vacuum distillation device, and distill under reduced pressure at 120°C to remove unreacted Eugenol and solvent toluene were cooled to obtain 18.7 g of a colorless viscous transparent liquid 2Si-PH with a yield of 80.9%.

[0031] Use Nicolet Impact410 Fourier Transform Infrared Spectrometer to measure the infrared spectrum of 2Si-PH and eugenol, the scanning range is 4000~400cm -1 , resolution 4cm -1 , KBr tablet, see the results figure 1 . Depend on figure 1 It can be seen that the C=C bond absorption peak in eugenol has disappeared in 2Si-PH, and the characteristic peak of Si-O bond appears in the reacted 2Si-PH, indicati...

Embodiment 2

[0035] Add 2Si-PH monomer, biphenol, dichlorodiphenyl sulfone and sodium carbonate into a nitrogen-protected container, use sulfolane as a solvent, and use toluene as a water-carrying agent, heat up to 150°C, and react with water to form a salt for 4 hours . The temperature was raised to 180°C for 2 hours, the temperature was raised to 200°C for 2 hours, and then the temperature was raised to 220°C for 2 hours. Discharge in deionized water, pulverize, and wash with water and ethanol three times respectively to prepare polyarylethersulfone 1 and polyarylethersulfone 2-5 with main chain containing Si-O-Si structure. The feed ratio and production rate are shown in Table 1.

Abstract

The invention relates to a polyarylether sulphone resin with a Si-O-Si structure in a main chain and a preparation method of the resin. The preparation method comprises the steps of: carrying out hydrosilylation reaction on a 1, 1, 3, 3-tetramethyl disiloxane-1, 3-bi (3-methoxy-4-propyl phenol) monomer with the Si-O-Si structure by taking 1, 1, 3, 3-tetramethyl dihydro-disiloxane and eugenol as raw materials, using toluene as a solvent for one-step synthesis; and carrying out random copolycondensation on the monomer, biphenol and dichloro-diphenyl sulfone under the condition that sulfolane is taken as a solvent to obtain the polyarylether sulphone resin. The preparation method is simple in synthetic route and available in raw materials; and the prepared polyarylether sulphone resin has excellent heat resistance, dissolubility and oxidation stability, thus the polyarylether sulphone resin is good in industrial application prospect.

Description

technical field [0001] The invention belongs to the technical field of macromolecule chemical synthesis, and in particular relates to a hydrophobic polyarylethersulfone resin containing a Si-O-Si structure in the main chain and a preparation method thereof. Background technique [0002] Silicone material is a new type of synthetic material with excellent performance. It has the dual properties of inorganic materials and organic materials. It can be made into a large number of intermediates, oils, elastomers and resins. It is a leader in synthetic materials. , known as industrial vitamins. Silicone materials have the advantages of low surface energy, good chain flexibility, hydrolytic stability, oxidation resistance and insulation, etc., so silicone materials are widely used in the field of hydrophobic materials. [0003] Silicone hydrophobic materials have self-cleaning effect and good biocompatibility, and have potential application value in biology, medicine, environmenta...
