Ball milling technique was applied to prepare binary mixtures of poly(ether
imide) (PEI) with poly(ethylene terephthalate) (PET), poly(butylene tereph
thalate) (PBT), and poly(ether ether ketone) (PEEK). From differential scan
ning calorimetry (DSC) and X-ray diffraction (XRD) measurements, we have an
alyzed the influence that PEI has on the thermal behavior of these mixtures
. A comparison with the blends formed by conventional methods has been perf
ormed. (C) 2000 Elsevier Science Ltd.
