Description
Summary:Liquid polybutadiene (PBLH) was modified with maleic anhydride (MA). The material (PBLHM) was characterized and used to prepare hybrid materials by blending with glycerol-plasticized cassava starch (TPS) and an organophilic clay at 5 wt% content. Processing was performed by extrusion under mild conditions and led to TPS/PBLHM/clay hybrids, at 95/5 to 85/15 TPS/PBLHM compositions, which were characterized by contact angle measurements, X-ray diffraction and mechanical analysis. The results revealed a reduction in the hydrophilicity and the reinforcement of the hybrid materials. Biodegradability tests showed that the addition of clay and of PBLHM led to materials with high biodegradability.
