Abstract The competition between cocrystallization and phase segregation in blends of poly(3-hydroxybutyrate) (PHB) and poly(3-hydroxybutyrate- co -3-hydroxyvalerate) (PHB–HV) containing 9 and 15% HV has been studied by 13 C cross-polarization magic-angle sample spinning (CPMAS) NMR and DSC techniques. The PHB homopolyester samples with selectively

Water sorption and diffusion have been investigated in poly(3-hydroxybutyrate) (PHB) and three poly(3-hydroxybutyrate-co-3-hydroxyvalerate) copolymers [P(HB-HV)] by means of a Cahn electromicrobalance. Permeability of these samples have been determined using a gravimetric permeation cell.

Production of poly(3-hydroxybutyric acid) [P(3HB)] by Rhodopseudomonas palustris SP5212 isolated in this laboratory has been optimized under phototrophic microaerophilic conditions. Cells grown in malate medium accumulated 7.7% (w/w) P(3HB) of cellular dry weight at the early stationary phase of growth. The accumulated P(3HB) however, attained 15% (w/w)

Poly(3-hydroxybutyrate) {P(3HB)} and the copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) {P(3HB-co-3HV)} were irradiated with γ-rays at 25°C in air and in vacuum. Melting points (Tm) and glass-transition temperatures (Tg) were measured by differential scanning calorimetry.

AbstractThe thermal degradation of poly(3‐hydroxybutyrate) (PHB) and poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) [P(HB‐HV)] was studied using thermogravimetry (TG). In the thermal degradation of PHB, the temperature at the onset of weight loss (To) was derived by To = 0.97B + 259, where B represents the heating rate (°C/min).
