摘要
合成了一系列酚酞型聚芳醚腈共聚物,并通过IR、DSC和TGA对共聚物的结构及热性能进行了研究,测定了共聚物的溶解性能及力学性能.共聚物具有很好的热稳定性和很高的玻璃化转变温度(Tg>200℃)、优良的机械性能(σy>104MPa)、较佳的断裂韧性(断裂伸长率>18%)
A series of poly(cyanoarylether) copolymers containing phenolphthalein segments were successfully synthesized.The structure and thermal property of the copolymers were studied by IR,DSC and TGA.The soubility and mechanical properties were also tested.It has been proved that the copolymer has very high glass transition temperature (T g>200 ℃),high tensile strength(σ Y>104 MPa),good fracture toughness(elongation at break above 18%) and satisfactory solubility.
