摘要
A novel triphenylphosphine-contained poly(ether ether ketone ketone) was synthesized from bis[4-(p-fluorobenzoyl)-phenyl]phenylphosphine oxide and hydroquinone by nucleophilic copolycondensation with sulfolane as the solvent. The structure was confirmed via FTIR, 31P NMR and 1H NMR. Electrical property, mechanical property, heat-resistance property, flame resistance and solubility were also evaluated. The results show that the polymer has an excellent heat-resistance, the glass transition temperature(Tg) is 212.6 ℃. The 5% mass loss of the polymer in nitrogen atmosphere took place at 476 ℃. The polymer is soluble in many organic solvents, such as CH2Cl2, CHCl3, Cl2(CH)2Cl2, Cl(CH2)2Cl, DMF, and NMP at room temperature, the polymer possesses well film ability, good mechanics property, electrical property, and the LOI is 44 which indicates that it possesses an excellent flame retardancy.
A novel triphenylphosphine-eontained poly （ ether ether ketone ketone） was synthesized from bis [ 4- （p-fluorobenzoyl）-phenyl ] phenylphosphine oxide and hydroquinone by nueleophilie eopolyeondensation with sulfolane as the solvent. The structure was confirmed via FTIR, ^31P NMR and ^1H NMR. Electrical property, mechanical property, heat-resistance property, flame resistance and solubility were also evaluated. The results show that the polymer has an excellent heat-resistance, the glass transition temperature（Ts） is 212.6 ℃. The 5% mass loss of the polymer in nitrogen atmosphere took place at 476 ℃. The polymer is soluble in many organic solvents, such as CH2Cl2, CHCl3, Cl2 （CH）2Cl2, Cl（ CH2）2Cl, DMF, and NMP at room temperature, the polymer possesses well film ability, good mechanics property, electrical property, and the LOI is 44 which indicates that it possesses an excellent flame retardancy.
