摘　　要：将氯端基聚醚醚砜齐聚物和杂萘联苯类双酚羟端基齐聚物通过溶液缩聚,成功地合成了一系列新型聚醚醚砜-聚醚砜(PEES-PPES)嵌段共聚物,并用IR、DSC、TGA、X-WAXD等测试手段对聚合物进行了表征。结果表明:PEES-PPES具有较高的热稳定性,较好的溶剂溶解性;砜基比例的变化对PEES-PPES的热性能有较大的影响,表明砜基对杂萘联苯聚醚砜改性效果明显。It synthesized a series of new-type of PEES- PPES block copolymers with hydroxylterminated PPES oligomer and 4-（4-Hydroxyphenyl）-2, 3-phthalazin-1-one （DHPZ） chloroterminated PEES oligomer by means of solution polycondensation method, and characterized the block copolymer by making use of IR, DSC, TGA, and X-WAXD. The results showed that the PEES-PES copolymer possessed high thermal stability and good solubility. The proportion of sulfuryl has great effect on the thermal properties of PEES-PPES, and the modification exhibited the tangible effect of sulfuryl on 4-（4-Hydroxyphenyl）-2,3-phthalazin-1-one（DHPZ） poly（ether sulfone） s.
