Thermal and morphology studies were carried out to characterize the mutual miscibility of poly(ethylene oxide)/poly(vinyl acetate) (PEO/PVAC) blends. The techniques used were DSC and polarized microscopy and the study covered the complete composition range. Morphology revealed qualitative difference
## Abstract Poly(vinyl acetate) (PVAc) was added to the crystalline blends of poly(ethylene oxide) (PEO) and poly(L‐lactide) (PLLA) (40/60) of higher molecular weights, whereas diblock and triblock poly(ethylene glycol)–poly(L‐lactide) copolymers were added to the same blend of moderate molecular w
Poly(ethylene oxide), poly(vinyl alcohol), and their blend in a 40 : 60 mole ratio were doped with aluminum isopropoxide. Their structural, thermal, and electrical properties were studied. Aluminum isopropoxide acts as a Lewis acid and thus significantly influences the electrical properties of the p
