TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The salt-forming agent is carbonate anhydrous potassium, cesium carbonate or anhydrous sodium carbonate.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (claimed): 4-Methoxy benzaldehyde, acetophenone, urea and elemental iodine in molar ratio of 2:2:4:1 are mixed, heated to 120 degrees C for 30 minutes and then poured into ethanol, precipitate is filtered, washed with ethanol, dried, and recrystallized using anhydrous ethanol, to obtain intermediate (I). The intermediate (I) is reacted with N,N-dimethylaniline dissolved in phosphorus oxychloride, heated for 7 hours under reduced pressure to remove the excess phosphorus oxychloride, and the resulting viscous oil is added to mixture of ice-water, stirred, and the precipitate is filtered off and dried, and recrystallized, to obtain white flakes crystal intermediate (II). Anhydrous nickel chloride, triphenylphosphine and zinc in molar ratio of 1:4-5:1 are mixed under the protection of inert gas mixture, N,N-dimethylformamide and anhydrous nickel chloride are added to mixture and reacted at 30-90 degrees C for 1 hour. Then, 0.05-0.08 mol/L of intermediate (II), N-di dimethylformamide solution and anhydrous nickel chloride in molar ratio of 0.8-1.2:1 are mixed, heated at 50 degrees C for 6 hours, extracted with chloroform, and organic phase is dried using anhydrous potassium sulfate, N,N-dimethylformamide is removed under reduced pressure, and washed with n-hexane to obtain intermediate (III). Then, pyrimidine hydrochloride and intermediate (III) are mixed in ratio of 1:35-50, heated to 175 degrees C for 8 hours, cooled to 120 degrees C, water is added and filtered, to obtain 4,4'-bis(4-hydroxyphenyl)-6,6'-biphenyl-2,2'-bipyrimidine (I).    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The polyarylether polymer is of formula (I).M+N=1;X=-S(=O)(=O)-, -C(=O)-, or group of formula (a);andY'=-S(=O)(=O)-, -C(=O)-, -C(-CH3)2-, or -C(-CF3)2-.Preferred Components: The bisphenol is 4,4'-dihydroxy benzophenone, bisphenol S, bisphenol A or bisphenol AF. The fluoromonomer is 4,4'-difluoro diphenyl sulfone, 1,4-bis(p-fluorobenzoyl)benzene or 4,4'-difluoro-benzophenone. The organic solvent is sulfolane, N,N'-dimethylacetamide, dimethylsulfoxide, N-methylpyrrolidone or sulfone. The azeotropic dehydration agent is toluene or xylene.
