研究了十四种不饱和羧酸酐的 N-苯基二酰亚胺的热聚合反应,以此作为“PMR”聚酰亚胺封端剂的选择。对结构与热聚合活性的关系进行了讨论。对其中五种热聚合速度较快的化合物,研究了它们的酸酯与苯胺在无水乙醇浓溶液中的反应动力学,求得反应速度常数、活化能和半衰期。 The thermal polymerization of fourteen unsaturated carboxylic anhydrides of N-phenyl diimide was studied as an option for “PMR” polyimide capping agent. The relationship between structure and thermal polymerization activity is discussed. Among the five compounds, the kinetics of the reaction between an ester and aniline in absolute ethanol was studied. The reaction rate constant, activation energy and half-life were obtained.
