Abstract

The miscibility of polyimide (PBPI-E)/polyimide (PTI-E) blends prepared by solution blending was studied by DSC and DMA techniques. The results obtained indicate that the blends are miscible for all compositions. Meanwhile, the unusual glass transition behaviour of the blends is discussed in terms of the changes of inter- and intramolecular charge-transfer interaction in the blends.
