21] confirm the possibility of inserting hydroxyvalerate
units (HV) between polymeric chains.
Microencasulation studies: characterization of hydrocortisone-loaded poly-hydroxybutirate- hydroxyvalerate
Besides PHB, its copolymers with diverse ratios of hydroxyvalerate
(HV) which are known as polyhydroxybutyrate-valerate (PHBV) are also extensively used.
A single species of bacteria converts corn and potato feedstocks into a copolymer of polyhydroxybutyrate (PHB) and hydroxyvalerate
Such effects could be due to presence of hydroxyvalerate
(HV) oligomeric units  which may agglomerate with CNCs in presence of simulant (ethanol) leading to the change in the appearance of PHB/CNC films to whitish color.
(PHBV) with different molar ratios of hydroxyvalerate
(HV) is known to be biodegradable and biocompatible, and its various properties such as natural origin, biodegradability, biocompatibility, optical activity, and thermoplasticity make it suitable for a variety of applications in health industry [12, 13].
Poly (3-hydroxy butyrate-co-3-hydroxy valerate) (PHBV) with 5 mol% hydroxyvalerate
content (PHB5V) was used in both white powder (trade name ENMAT Y1000) and pellet (Y1000P) forms as obtained from Tianan Biologic Materials Company, Ningbo, China.
Biopol was actually a copolymer of hydroxybutyrate and hydroxyvalerate
known as PHBV, which is slightly more flexible than standard PHB.
1054--Thermal And Rheological Properties Of PHB Synthesized With Various Hydroxyvalerate
Content For Potential Use In Food Packaging
It was also reported that increasing the level of hydroxyvalerate
comonomer in the copolymer led to reduced thermal degradation.
The most extensively studied member of PHAs is poly(3-hydroxybutyrate) (PHB) and its copolymers, poly(3-hydroxybutyrate-co-3-hydroxyvalerate
) (PHBV) with varying ratios of hydroxyvalerate
, PHBV is synthesized by many bacteria as intracellular carbon and energy storage material from agricultural feedstocks, such as sugars and plant oils.
Poly (3-hydroxyhuiviate-co-3-hydroxyvaletate) (PHBV) with 5% hydroxyvalerate
content and trade name ENMAT Y1000 was obtained from Tianan Biologic Materials Company.
