On the Mechanical and Thermal Behavior of PLA, PBAT, and PHBV‐Based Ternary Blends and the Effect of Short Flax Fibers as Reinforcing Agents

Polymer Composites, EarlyView.
Preparation and testing of biodegradable polymer ternary blends and composites with short flax fibres. ABSTRACT Bioplastics offer environmental benefits but they are costly and exhibit lower mechanical and thermal performance compared to fossil‐based counterparts. Poly(butylene adipate‐co‐terephthalate) (PBAT) exhibits high ductility but relatively low

Immiscibility phenomenon in low density branched polyethylene, PEED, films in blown film extrusion process

CT&F - Ciencia, Tecnología y Futuro, 2000
The immiscibility in branched low-density polyethylene film was researched using techniques of instrumental analysis (FTIR, DRX, DSC, TGA, SEC-GPC, SEM-EDX) and rheometry (DMA, Capillary Rheomether). It was determined that immiscibility occurs when there are microentities generated by an undesirable polymer found in a low proportion in the mixture ...
