Sn. Yau et Em. Woo, MISCIBILITY IN A TERNARY-SYSTEM OF POLY(ETHER IMIDE) WITH SEMICRYSTALLINE POLY(ETHYLENE-TEREPHTHALATE) AND POLY(BUTYLENE TEREPHTHALATE), Macromolecular rapid communications, 17(9), 1996, pp. 615-621
A rare case of thermodynamic miscibility has been demonstrated in the
amorphous state (quenched glass as well as molten state) of a ternary
blend system formed by poly(ether imide) and semicrystalline poly(ethy
lene terephthalate) and poly-(butylene terephthalate). A single glass
transition temperature (T-g) in the ternary blends was observed using
differential scanning calorimetry and dynamic mechanical analysis.
