Blending PHB with another bio-based and/or biologically degradable material. Poly-hydroxybutyrate (PHB) is blended with another biodegradable polymer called Galactomannon. Preparation of copolymers of PHB with other natural polymers (viz., Cassia gum, Tamarind seed, Xanthan gum, Alginates).Copolymerization technique was also employed as a modification technique in addition to blending and both the techniques were compared. Analyze the physico-mechanical properties of copolymers using various

Blend films were evaluated and characterized by Fourier transform infrared spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). Moisture absorptivity studies were also carried out for the various blend films. This to, be a good option to develop PHB blends maintaining its biodegradability and bioreabsorption properties.
