Abstract
The new composite material based on arylalicyclic polyimide and poly(ethylene terephthalate) are being reported. Synthesis and blend preparation methods and their physical-chemical and physical-mechanical properties were investigated. It was observed widening of bands in FTIR spectra, in comparison with the composites reported from our earlier studies. However, it was not detected any physical-chemical interactions between two ingredients of the blend, which could be characterized as a typically compatible polymer blend at the content of PETP up to 25 wt.%. Such new polyimide composite could be utilized as devices, which show both high thermoresistance and stability of polyimide and elastic properties of poly(ethylene terephthalate).
