中文摘要	miscibility, crystallization, and mechanical properties of blends of thermosetting polyimide pmr-15 and phenolphthalein poly(ether ketone) (pek-c) were examined. with the exception of the 90/10 blend, which has two glass transition peaks, all the blends with pmr-15 less than 90 wt % are miscible in the amorphous state according to dma results. addition of pek-c hindered significantly the crystallization of pmr-15, indicating that there must exist some kind of interaction between molecular chains of pmr-15 and those of pek-c. the semi-ipn system of pmr-15/pek-c blends exhibits good toughness. two distinct microphases, interweaving at the phase boundaries, were found in the pmr-15/pek-c 60/40 blend. the toughness effect of the blends is discussed in terms of the interface adhesion between the two distinct phases and the domain sizes of the phases. the relation between miscibility and toughness of the blends was investigated.
