摘　　要：Based on several unsymmetrical, twist, noncoplanar phthalazinone-containing monomers 2a-2e and an active bis（4-fluorophenyl）phenyl phosphine oxide （BFPPO） monomer, a series of novel poly（phthalazinone ether phosphine oxide）s （PPEPO） was synthesized by anhydrous K2CO3 mediated N-C coupling reaction in DMAc. The polymers exhibited good thermal properties with Tgs ranging from 267℃ to 306℃ and 5% weight loss temperatures in nitrogen higher than 430℃, together with high char yield upon prolonged heating at 800℃ （35%-56%）. Moreover, the polymers were readily soluble in common organic solvents, such as N-methyl-2-pyrrolidone, chloroform and m-cresol. These polymers had inherent viscosities in the range of 0.45-0.72 dL/g and could be cast into flexible and colorless films by spin coating or casting approach.Based on several unsymmetrical, twist, noncoplanar phthalazinone-containing monomers 2a-2e and an active bis（4-fluorophenyl）phenyl phosphine oxide （BFPPO） monomer, a series of novel poly（phthalazinone ether phosphine oxide）s （PPEPO） was synthesized by anhydrous K2CO3 mediated N-C coupling reaction in DMAc.
