SYNTHESIS AND CHARACTERIZATION OF A PHOSPHORUS-CONTAINING POLY(ETHER ETHER KETONE KETONE SULFONE)

A new kind of phosphorus-containing monomer bis（4-（p-fluorobenzoyl）phenyl）phenylphosphine oxide was synthesized first,then a poly（aryl ether ketone） containing phosphorus in the main ring was synthesized,derived from bis（4-（p-fluorobenzoyl）phenyl）phenylphosphine oxide and bisphenol-S by nucleophilic copolycondensation with the use of sulfolane as solvent.The structure was confirmed by FT-IR,（）31P-NMR and（）1H-NMR.Electrical property,mechanical property,heat-resistance property,combustion-resistance and solubility was also researched to know the influence of the containing of phosphorus.The results showed that the polymer have excellent heat-resistance,the glass transition temperature（Tg） was 235℃.The onset temperature taken at 5% weight loss of the polymer in nitrogen was 463℃.The polymer was soluble in CH2Cl2,CHCl3,Cl2（CH）2Cl2,Cl（CH2）2Cl and strongly polar organic solvents such as（N,N-dimethylformamide）（DMF）,N-methyl2pyrrolidone （NMP） at room temperature.
