Blends of native corn starch and poly(ethylene-co-vinyl alcohol) (EVOH), with starch : EVOH ratios of 1 : 1 (SE-50) and 2 : 1 (SE-67A, SE-67B), were processed into blown films. SE-67A had a higher glycerol and water content and was processed at 5ЊC higher than was SE-67B. The films were conditioned
## Abstract Differential scanning calorimetry, thermogravimetric analysis, X‐ray diffraction, and ultraviolet–visible spectroscopy of gelatin and poly(vinyl alcohol) (PVA) homopolymers and their blended samples were studied. The data revealed that the gelatin and PVA polymers were compatible over t
The melting temperature of the gels of the poly(vinyl alcohol) (PVA)/ethylene glycol (EG) system was measured. It was found that the temperature was independent of the thermal hysteresis. The apparent enthalpy of the fusion of the junction, DH, was 206 kJ/mol for a high molecular weight atactic PVA
## Abstract The miscibility behavior and morphology of a series of poly(vinyl butyral‐__co__‐vinyl alcohol) (PVBA) copolymers containing 29, 52, 76, and 88 mol % of vinyl alcohol units with poly(ethylene terephthalate‐__co__‐ethylene naphthalate) (PETN) was investigated by DSC and SEM. Blends of th
