| 英文摘要 | PMR type of poly(pyrrolone-benzimidazole) copolymers (PPBI) were synthesized by the poly-condensation of monoethyl ester of cis-5-norbomene-endo-2,3-dicarboxylic acid (NE), diphenyl-isoplithalate (DPIP), diethyl ester of 4,4'-oxydiphthalic acid (ODPE) and 3,3-diaminobenzidine (DAB) or 3,3',4,4'-tetraamindiphenyl ether(TAD) in a mixing solution of anhydrous ethyl alcohol and N-methyl-pyrrolidone (NMP) under different temperature and pressure procedures. The resulting resin solution showed an excellent solubility in polar organic solvents and good stability at room temperature, while the corresponding PPBI molded powder and molded plate could be prepared by undergoing amidation, imidization, cyclization and crosslinking reactions when the reaction temperature would be increased from 150 to 350 degreesC, especially, the crosslinking structure formed by the reverse Dials-Alder displayed by the pressure meter. The chemical reactions and properties of the resulting PPBI molded powders and molded plates were studied by means of FT-IR, TGA, DMA methods, and the results indicate that the PPBI materials obtained hold excellent thermal stability and processability, the initial decomposition temperature > 600 degreesC and its T-g defined by the peak temperature in tan 6 curve from the DMA method is 448 degreesC (DAB) or 423 degreesC (TAD) for PPBI-20 molded plate. |
