Poly(lactic acid) (PLA) and poly(ethylene glycol) (PEG) were melt-blended and extruded into films in the PLA/PEG ratios of 100/0, 90/10, 70/30, 50/50, and 30/ 70. It was concluded from the differential scanning calorimetry and dynamic mechanical analysis results that PLA/PEG blends range from miscib
The miscibility of binary blends of bacterial poly[(R)-3-hydroxybutyric acid] {P[(R)-3HB]} (Mw = 650 000) with poly[(S)-lactic acid] {P[(S)-LA]} of various molecular weights (Mw = 9900-530 000) have been studied by means of differential scanning calorimetry (d.s.c.). D.s.c. analysis revealed that th
## Abstract Miscibility of poly(ethyloxazoline) (PEOX) with poly(vinyl acetate) (PVAC), poly(vinyl alcohol) (PVAL) and poly(vinyl acetate‐__co__‐vinyl alcohol) (ACAL copolymers) has been investigated over a wide composition range. In some blends, due to the small difference between the glass transi
