WebIn the present paper PLA based blends containing PBAT or PBS were employed for producing films by blown film extrusion. A reactive plasticizer was used in extrusion laboratory trials to both increasing flexibility and improve compatibility, then the process was scaled up in a semi-industrial extruder to prepare pellets adding also LAK 301 as ... WebApr 17, 2015 · Second, a reactive extrusion process was developed to covalently anchor dPHB onto the main chain of PLA. PLA with 20% (w/w) grafted dPHB demonstrated an impressive elongation at break of 538%, 66 times higher than that of pure PLA and significantly higher than the elongation at break of the corresponding physical blend. WebOct 27, 2024 · Abstract Blending with biodegradable poly (butylene succinate) (PBS) is an effective way for improving the performance of PLA reactive extrusion. Multifunctional monomer trimethylolpropane tri-acrylate (TMPTA) is used as chain extender to react with PLA and PBS to generate graft copolymers at the PLA/PBS interface. the pilot pocket
