Microencapsulation of antibiotic rifampicin in poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [PDF]

Archives of Pharmacal Research, 2008
The aim of this study was the preparation of microparticles containing rifampicin using a biodegradable polymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) for oral administration produced by a bacteria. The poly(3-hydroxybutyrate-co-3-hydroxyvalerate) microparticles with and without rifampicin were prepared by the emulsification and solvent ...

Co-crystallization of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

Journal of Materials Science, 1992
A combined study of X-ray diffraction, differential scanning calorimetry and density measurements in copolymers of 3-hydroxybutyrate and 3-hydroxyvalerate is presented. It is shown that the unit cell volume expands linearly with the comonomer content in the polymer.

Isothermal crystallization of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

European Polymer Journal, 2003
Isothermal crystallization behavior of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was investigated by means of differential scanning calorimetry and polarized optical microscopy (POM). The Avrami analysis can be used successfully to describe the isothermal crystallization kinetics of PHBV, which indicates that the Avrami exponent n = 3 is good

Properties and Applications of Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) Biocomposites

Journal of Polymers and the Environment, 2020
Polyhydroxyalkanoates (PHAs) are biopolyesters accumulated by microorganisms as intracellular storage materials and they have attracted attention as “green plastic” alternatives to their petrochemical counterparts. Poly(3-hydroxybutyrate-co-3-hydroxyvalerate), PHBV, is one of the most studied members of the PHAs family, with numerous applications. PHBV

Anaerobic degradation of poly-3-hydroxybutyrate and poly-3-hydroxybutyrate-co-3-hydroxyvalerate

Biodegradation, 1997
The anaerobic degradation of the polyesters poly-3-hydroxybutyrate (PHB) and poly-3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV) was investigated with special regard to intermediate products, kinetics, and yields. During the degradation of PHBV acetate, propionate, n-butyrate, and n-valerate were detected.

Surface grafting of cellulose nanocrystals with poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

Carbohydrate Polymers, 2014
Chemically modified cellulose nanocrystals (CNCs) were synthesized by grafting poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) onto CNCs via homogeneous acylation reaction between N,N-dimethyl formamide (DMF) by using toluene diisocyanate (TDI) as coupling agent and dibutyltin dilaurate as catalyst. The resulting copolymers were studied by using (1)
