Thermal behavior and intermolecular interactions in blends of poly(3‐hydroxybutyrate) and maleated poly(3‐hydroxybutyrate) with chitosan

Journal of Polymer Science Part B: Polymer Physics, 2004
AbstractThe thermal behavior and intermolecular interactions of blends of poly(3‐hydroxybutyrate) (PHB) and maleated PHB with chitosan were studied with differential scanning calorimetry, Fourier transform infrared (FTIR), wide‐angle X‐ray diffraction (WAXD), and X‐ray photoelectron spectroscopy (XPS).

Carbon dioxide sorption and diffusion in poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-CO-3-hydroxyvalerate)

Journal of Applied Polymer Science, 1999
CO 2 sorption and diffusion in poly(3-hydroxybutyrate) and three poly(3-hydroxybutyrate-co-3-hydroxyvalerate) copolymers were investigated gravimetrically at temperatures from 25° to 50°C and pressures up to 1 atm. The sorption behavior proved to be linear for all the copolymers studied.

Biodegradable Poly(3‐hydroxybutyrate) Nanocomposite

Macromolecular Symposia, 2009
AbstractThis work seeks bringing a technological and social contribution by searching blends and composites of poly(3‐hydroxybutyrate) (PHB) and polyethylene widely used in packaging films, and colloidal silica. The mixtures were prepared by extrusion using a single‐screw extruder and were analyzed regarding their thermal and mechanical properties and ...

Anaerobic Production of Poly(3-hydroxybutyrate) and Its Precursor 3-Hydroxybutyrate from Synthesis Gas by Autotrophic Clostridia.

Biomacromolecules, 2019
Anaerobic production of the biopolymer poly(3-hydroxybutyrate) (PHB) and the monomer 3-hydroxybutyrate (3-HB) was achieved using recombinant clostridial acetogens supplied with syn(thesis) gas as the sole carbon and energy source.

ULTRASONIC DEGRADATION OF POLY(3-HYDROXYBUTYRATE)

2012
Određivanje vrijednosti molekulnih masa kao i neuniformnosti polimera od velike je praktične važnosti, jer većina fizičkih, kemijskih i uporabnih svojstava polimera znatno ovisi o tim vrijednostima. Molekulna masa polimera može se vrlo jednostavno odrediti mjerenjem viskoznosti razrijeđenih polimernih otopina, jer je povezana s viskoznošću polimerne ...
