| 中文摘要 | a novel synthesis of asymmetric bis(chlorophthalimide)s (3,4-bcpis) has been established. the polymerizations of them produced higher molecular weight (0.38-0.51 dl/g) polyimides containing biphenyl units than those of isomeric polymers derived from symmetric bis(chlorophthalimide)s (4,4'-bcpis) and 3,3'-bcpis. the distribution of the formed biphenyl units of head to tail, head to head, and tail to tail in the chain of the polymers was about 58.0:21.0:21.0, determined by c-13 nmr spectra of the polymers. the composition of model compounds, determined by hplc, was well consistent with the 13c nmr spectrum result. comparing with polymers derived from 4,4'-bcpis and 3,3'-bcpis, the polymers derived from 3,4-bcpis showed better solubilities in n,n-dimethylacetamide (dmac), n,n-dimethyl-formamide (dmf), and n-methylpyrrolinone (nmp). flexible films could be cast from the polymer solution with the inherent viscosities of above 0.35 dl/g. the polymer derived from asymmetric bis(chlorophthimide)s gave the highest t-g among the isomeric polymers. |
