Environmentally degradable plastics: thermal behavior of olymer blends based on waste gelatin

Abstract

Blends, based on waste gelatin (WG) and poly(vinyl alcohol) (PVA), formulated for agroindustrial applications are currently under investigation. In the present contribution their characterization by thermo-gravimetry (TG) and differential scanning calorimetry (DSC) is reported. The results obtained are compared with those of analogous blends based on "virgin" gelatin (VG). Whereas these last tended to phase segregate, those based on WG resulted compatible due to the presence of glycerol in WG and its inherent destructurization caused by former thermal and mechanical treatment.
