| 中文摘要 | 3,3-dichloro-n,n'-biphthalimide (3,3'-dcbpi), 3,4'-dichloro-n,n'-biphthalimide (3,4'-dcbpi), and 4,4'-dichloro-n,n'x-biphthalimide (4,4'-dcbpi) were synthesized from 3- or 4-chlorophthalic anhydrides and hydrazine in glacial acetic acid. the yield of 3,3'-dcbpi (90%) was much higher than that of 4,4'-dcbpi (33%) because of the better stability of the intermediate, 3-chloro-n-aminophthalimide, and 3,3'-dcbpi. a series of hydrazine-based polyimides were prepared from isomeric dcbpis and 4,4-thiobisbenzenethiol (tbbt) in n,n-dimethylacetamide in the presence of tributylamine. inherent viscosity of these polymers was in the range of 0.51-0.69 dl/g in 1-methyl-2-pyrrolidinone (nmp) at 30 degrees c. these polyimides were soluble in 1,1,2,2-terachloroethane, nmp, and phenols. the 5% weight-loss temperatures (t(g)s) of the polymers were near 450 degrees c in n-2. their glass-transition temperatures (t(g)s) determined by dynamic mechanical thermal analysis and differential scanning calorimetry increased according to the order of polyimides based on 4,4'-dcbpi, 3,4'-dcbpi, and 3,3'-dcbpi. the hydrolytic stability of these polymers was measured under acid, basic, and neutral conditions and the results indicated that the order was 3,3'-dcbpi/tbbt > 3,4'-dcbpi/tbbt > 4,4'-dcbpi/tbbt. |
