Thermoplastic starches (TPS) are important bio-based, biodegradable polymers used in flexible packaging. However, their mechanical properties, processability, and high hydrophilicity limit their applications. This study examines the effects of chemical modifications and mechanical reinforcements on TPS matrices. Combinations of native and acetylated TPS, reinforced with native (CNF) and acetyla...

To address plastic pollution from fossil fuel polymers, biodegradable alternatives like starch and polybutylene succinate (PBS) are proposed. However, starch is hydrophilic, while PBS and PBSA are hydrophobic. This research investigates the use of dicumyl peroxide (DCP) and tartaric acid (TA) as coupling agents in blends of thermoplastic starch (TPS) and PBS/PBSA, with glycerol as a plasticizer...

The 39th International Conference of the Polymer Processing Society (PPS-39) was hosted by Uni versidad de los Andes and ICIPC and attended by nearly 435 participants from 41 countries. Besides traditional symposia about polymer processing, the PPS-39 program included four special symposia on Biopolymers, Biocomposites, and Bioprocessings; Circular Economy of Polymers; Degradation; and Biodegra...
