中文摘要: 以偏苯三甲酸酐酰氯(TAAC)、1,4-二(4 苯氧基苯甲酰基)苯(p-EKKE)为单体,无水AlCl3、二氯乙烷(DCE)及N-甲基吡咯烷酮(NMP)为催化溶剂体系,通过低温溶液缩聚合成了含羧基侧基的聚芳醚酮酮醚酮酮(PEKKEKK-A)树脂。用红外光谱(FT-IR)、氢核磁共振(1H-NMR)、广角X射线衍射(WAXD)、热失重(TGA)、差热示差扫描(DSC)等技术对聚合物的结构与性能进行了表征,测定了聚合物的对数比浓黏度、酸值及溶解性能。结果表明:非晶聚集态PEKKEKK A树脂具有较高的玻璃化转变温度和热分解温度及优良的耐化学腐蚀性。
Abstract:Poly aromatic ether ketone ketone ether ketone ketone containing side carboxyl group (PEKKEKK-A) was synthesized from trimellitic anhydride acid chloride(TAAC) and 1,4-bis(4-phenoxybenzoyl) benzene(p-EKKE) by low temperature solution polycondensation of 1,2-dichloroethane(DCE), N-methy-2-pyrrolidone(NMP) and anhydrous aluminum chloride(AlCl3). The polymer was characterized by Fourier infrared spectrum(FT-IR), proton nuclear magnetic resonance(1H-NMR), wide-angle X-ray diffraction (WAXD), thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The relationship between inherent viscosity and acid value of polymer was also investigated. Results show that the polymer has high glass transition temperature, thermal decomposition temperature and excellent chemical-resistance.
