description Polyvinyl alcohol (PVOH) blends with cassava starch (CSS) is a biodegradable polymer compound. This polymer compound is suitable to be used as biodegradable material to reduce the accumulation of synthetic petroleum-based polymer solid wastes.

In addition, infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA) were conducted to support the molecular modeling outcomes. The processability behaviour of the PVOH-glycerol-CSS compounds (PGCS) such as specific heat capacity, pressure-volume-temperature, and shear rate-viscosity were studied as well.
