Analytical Assessment of Biodegradation Claims in Post-Consumer Polymer–Dextrin Composites: FTIR Identification, Phase Balance Constraints, and Removable Inventory Kinetics

Gravimetric mass loss in polymer–biogenic filler systems is often reported as polymer biodegradation without establishing which phase of the material is lost. This study proposes and applies an analytical framework that combines FTIR identification of the starting material, a pha...
