BIODEGRADABLE COMPOSITES BASED ON CELLULOSE ACETOBUTYRATE AND ORGANIC FILLERS

Biodegradable composites based on cellulose acetobutyrate (CAB) and organic fillers were obtained in the form of extruded tapes. Corn starch and rice husk were used as organic fillers. It was established that in the CAB – plasticizer – starch system, starch particles are relatively homogeneously distributed within the polymer matrix, with their integration facilitated by a binder composed of triacetin and glycerol monostearate. In contrast, the composite containing both starch and rice husk exhibited a heterogeneous filler distribution. It was also noted that the obtained samples underwent biodegradation in compost under laboratory conditions
