Miscibility and thermal behavior of blends of synthetic biodegradable aliph
atic polyester (BDP) with poly(epichlorohydrin) (PECH) were investigated by
both differential scanning calorimetry and a dynamic mechanical thermal an
alyzer. Single glass transition temperatures in agreement with the Fox equa
tion indicate that these blend mixtures are miscible. This was further clar
ified from the cryogenically fractured surface of BDP-PECH blends by scanni
ng electron microscopy. (C) 1999 Elsevier Science Ltd. All rights reserved.
