| Abstract: | The polymerization of fourteen N-phenyl unsaturated dicarboximides were studied for the selection of capping agents of "PMR" polyimides. The correlation between the polymerization activities and the structure of dicarboximides was discussed. The kinetics of five monoethyl ester of unsaturated dicarboxylic acids possessing higher polymerization activities with aniline in absolute ethanol were also investigated and their rate contants, activation energies and half lives were obtained. |
