Water transport, structure features and mechanical behavior of biodegradable PHB/PVA blends

A blend design on the basis of polymer components with different hydrophilicities is of academic and industrial interest, primarily for the control of such critical characteristics as water permeability, equilibrium sorption, and diffusional mobility. The greater the difference between the polarity of the blended macromolecules, the harder it is to achieve a scantily miscible blends' production. This blends' based on water-soluble and biocompatible PVA and PHB could be treated as new generation of environmentally protected materials in the packaging industry, for agricultural application and in biomedicine areas.
