Poly - aryl - phenyl ether derivatives are a class of high - performance polymer materials, and the common derivatives include polyaryl ether ketone and polyaryl ether sulfone. The detailed information is as follows:
- Polyaryl Ether Ketone (PAEK) Derivatives
- Main Varieties: According to the connection order and proportion of ether bonds, ketone groups and benzene rings in the molecular chain, various varieties can be formed, such as polyetheretherketone (PEEK), polyetherketone (PEK), polyetherketoneketone (PEKK), etc. Among them, PEEK is the most important and commonly used.
- Molecular Structure: The molecule contains benzene rings, ether bonds and carbonyl groups. The benzene ring endows it with rigidity, and the ether bond provides flexibility. This structure gives it excellent high - temperature performance, mechanical properties, electrical insulation, radiation resistance and chemical resistance.
- Performance Characteristics: It has a high glass - transition temperature and melting point. For example, the glass - transition temperature of PEEK is 143℃, the melting point is 343℃, and the heat - deflection temperature under load is as high as 316℃. It has high mechanical strength, both rigidity and flexibility, and outstanding fatigue resistance. It also has excellent self - lubrication, corrosion resistance (insoluble in any solvent, strong acid and strong alkali except concentrated sulfuric acid), flame retardancy, hydrolysis resistance, etc.
- Preparation Method: It is usually prepared by the polycondensation reaction of 4,4' - difluorobenzophenone and hydroquinone under the condition of alkali metal carbonate using diphenyl sulfone as a solvent.
- Application Fields: Widely used in aerospace, electronic and electrical, biomedical, automotive industry, petrochemical and other fields. For example, it can be used in bionic joints and lightweight gears of humanoid robots, and can also realize lightweight replacement of many parts in aerospace equipment.
- Main Manufacturers: Including Victrex in the UK, EVONIK in Germany, SOLVEY in Switzerland, Mitsubishi Chemical in Japan, etc. In China, there are Changchun Jida Special Plastics Engineering Research Co., Ltd., Jilin Zhongyan High - Performance Engineering Plastics Co., Ltd., etc.
- Polyaryl Ether Sulfone (PAES) Derivatives
- Main Varieties: Mainly include biphenyl - type polyaryl ether sulfone (PPSU) and bisphenol A - type polyaryl ether sulfone (PSU).
- Molecular Structure: It contains sulfonyl, ether bond and benzene ring structure. The presence of sulfonyl groups endows the material with good thermal stability, oxidation resistance and mechanical properties, while the ether bond gives it a certain degree of flexibility.
- Performance Characteristics: It has excellent chemical resistance, high - temperature stability and excellent mechanical strength. PPSU has extremely high heat resistance and strength, and PSU has good processability and comprehensive properties.
- Preparation Method: PPSU is prepared by the reaction of 4,4' - dichlorodiphenyl sulfone and biphenol in the solvent CBS/DMAc, and PSU is prepared by the condensation reaction of 4,4' - dichlorodiphenyl sulfone and bisphenol A as the main raw materials in the catalyst and solvent CBS/DMAc.
- Application Fields: PPSU is widely used in aerospace, medical equipment and other harsh - requirement fields, such as manufacturing medical device parts. PSU is mainly used in electronic and electrical, automotive manufacturing, food machinery and other industries, and can be used to produce battery enclosures, connectors, etc.
- Main Manufacturers: The global main production capacity is concentrated in Solvay in Belgium, BASF in Germany, Sumitomo Chemical in Japan and other enterprises. Domestic enterprises such as Shandong Haoran, Youju New Materials, 沃特股份 (Wotef 股份), Kingfa Sci. & Tech. Co., Ltd. also have a certain production capacity.
