Macroporous poly(3-hydroxybutyrate-co-3-hydroxyvalerate) matrices for bone tissue engineering
Biomaterials, 2003Macroporous poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV) matrices were prepared after solvent evaporation and solute leaching. PHBV solutions with different concentrations were prepared in chloroform: dichloromethane (1:2, v/v). In order to create a matrix with high porosity and uniform pore sizes, sieved sucrose crystals (75-300 or 300 ...

Biodegradable and biosourced poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) fiber was used as a reinforcing agent, and environment friendly poly(ɛ-caprolactone) (PCL) composites were prepared by melt compounding. The mechanical properties, rheological properties, and enzymatic degradation of the PCL composites were investigated in detail. With the

Particular thermal properties of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) oligomers
Journal of Polymer Research, 2011Telechelic hydroxylated poly(3-hydroxybutyrate-co-3-hydroxyvalerate)s (PHBV-diols) were synthesized by transesterification with ethylene glycol, which could be used as the macromonomers for synthesis of block copolymers. PHBV-diols owned particular thermal properties. PHBV-diols had much lower the melting temperatures (T

Synthesis of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) from activated sludge
Biotechnology Letters, 1997Poly-3-hydroxybutyrate (PHB) and poly(3-hydroxybutyrate- co-3-hydroxyvalerate) (PHBV) was produced using a co-culture of activated sludge. When butyric acid was used as sole carbon source, PHB was produced. When valeric acid was added to the medium, PHBV was produced.

Biodegradability of poly (3-hydroxybutyrate-co-3-hydroxyvalerate) in activated sludge
Chemosphere, 1992Abstract The biodegradability of microbial copolyester of 3-hydroxybutyrate and 3-hydroxyvalerate, P(3HB-co-3HV), in activated sludge was studied by MITI test method to examine the applicability of the test to biodegradable plastics. The biodegradability after 28 days was 88% under standard condition and did not vary with the particle size of test ...

Enzymatic degradation of blends containing poly(3-hydroxybutyrate-co-3-hydroxyvalerate)
Polymer Degradation and Stability, 1994The enzymatic degradation of blends of poly(β-hydroxybutyrate-co-16% β-hydroxyvalerate) with polystyrene, and styrene-acrylonitrile copolymers was studied. Degradation has been measured by weight loss after exposures to the extracellular depolymerase from Penicillium funiculosum.

Modified poly(3-hydroxybutyrate-co-3-hydroxyvalerate) using hydrogen bonding monomers
Polymer, 2004Properties of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) were significantly modified by a hydrogen bonding (H-bond) monomer-bisphenol A (BPA). BPA lowered the T-m of PHBV and widened the heat-processing window of PHBV. At the same time, a dynamic H-bond network in the blends was observed indicating that BPA acted as a physical cross-link agent.

Miscibility of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and poly(vinyl chloride) blends
Polymer, 1995Abstract The miscibility behaviour of biodegradable poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHB-HV) blended with poly(vinyl chloride) (PVC) was investigated by using differential scanning calorimetry, dynamic mechanical thermal analysis, Fourier-transform infra-red spectroscopy and a mechanical testing system. A blend of PHB-HV containing 8% HV
