Problems solved by technology

However, both hyperbranching and grafting reactions have their limitations. For example, hyperbranching reactions tend to cause crosslinking of the reaction system during polymerization, while grafting reactions cannot hybridize cage silsesquioxanes into the main chain.
However, research on the dielectric and hydrophobic properties of polyarylethersulfone resins containing cage silsesquioxane in the main chain is rarely reported in relevant literature and patents.

Embodiment 1

[0025] Add 2Si-OH monomer, bisphenol A, dichlorodiphenyl sulfone and potassium carbonate into a nitrogen-protected container, use sulfolane as a solvent, and use toluene as a water-carrying agent. Raise the temperature to 150°C, and react with water to form a salt for 4 hours. The temperature was raised sequentially to 180, 200 and 220°C for 2 hours each. Discharge in deionized water, pulverize, wash with water and ethanol three times respectively to prepare polyarylether sulfone 1 and polyarylether sulfone 2-6 with cage organosilsesquioxane double deck structure in the main chain. The feed ratio and production rate are shown in Table 1.

Abstract

The invention discloses polyarylether sulphone resin with a main chain containing a cage-type silsesquioxane double-deck structure and a preparation method thereof, and belongs to the technical field of high polymer chemistry. The polyarylether sulphone resin is prepared by taking 3,13-bis(2-methoxy-4-propyl phenol) octaphenyl cage-type silsesquioxane, bisphenol and dichlorodiphenyl sulphone as reactants, taking sulfolane as a solvent and taking potassium carbonate as a salt forming agent through heating to 150-170 DEG C, and carrying out a water-carrying salifying reaction for 2-4 h; then, respectively heating to 180-190 DEG C, 200-210 DEG C and 210-220 DEG C to react 2-4 h; discharging obtained materials to deionized water, crushing the obtained object, and respectively washing the obtained product 3-5 times by using water and ethanol, so that the polyarylether sulphone resin with the main chain containing the cage-type organic silsesquioxane double-deck structure is obtained. The polyarylether sulphone resin disclosed by the invention is simple in synthetic route, and easily-obtained in raw materials; because the prepared polyarylether sulphone random copolymer resin has excellent heat resistance, low dielectric properties and hydrophobicity, therefore, the polyarylether sulphone resin has a good industrial application prospect.

Description

technical field [0001] The invention belongs to the technical field of polymer chemistry, and in particular relates to a polyaryl ether sulfone resin whose main chain contains a cage-type silsesquioxane double deck structure and a preparation method thereof. Background technique [0002] Polyarylethersulfone resin is a high-performance special engineering plastic with high strength, low density, heat resistance, wear resistance, radiation resistance and chemical corrosion resistance, etc. It is widely used in aerospace, automotive, electrical and electronic, chemical industry , machinery and medical fields. However, the introduction of sulfone groups in polyarylethersulfone resins has an adverse effect on its hydrophobic properties. The modification of polyarylethersulfone has been the main direction of research in recent years, such as introducing side groups, functional groups or semi-distorted non-planar structures on the main chain to change the hydrophobicity, ductilit...
