中文摘要	the miscibility and morphology of polyimide/polyimide blends, pei-e/pti-e(a)) and pbpi-e/ipti-e(a)), have been studied by means of c-13 cpmas nmr technique. the results indicate that pei-e/pti-e blends are miscible on a molecular level, but molecular aggregation exists in pure pbpi-e specimen as well as pbpi-e/pti-e blends with high content of pbpi-e, which vanishes in the blends with high content of pti-e. when the content of pbpi-e is higher than that of pti-e, the addition of pti-e to pbpi-e has almost no effect on the size of the pbpi-e rigid domains, but has a large effect on the populations of the pbpi-e rigid domains. it is the intermolecular charge-transfer interaction that plays a critical role in the miscibility of pei-e/pti-e and pbpi-e/pti-e blends.
