Pretreatment Effects of Conventional and Reactive Extrusion on LLDPE Waste Pyrolysis

Polymer Engineering &Science, EarlyView.
Schematic overview of the pyrolysis study using original and pretreated LLDPE waste samples. Pretreatment was performed via twin‐screw extrusion at 450°C: without additives (REX), with peroxide (REX‐RO2), or with polypropylene (REX–PP). All four samples underwent pyrolysis at 450°C–475°C for 15–45 min.

Compatibilization and Reinforcement of PHB/PBAT Blends via Sequential Blending of Surface‐Modified Cellulose

Polymer Engineering &Science, EarlyView.
Sequential blending improved the mechancial properties of PHB/PBAT/cellulose composites as compared to the one‐step batch mixing method. ABSTRACT Polyhydroxybutyrate (PHB) is a natural and biodegradable polymer generated by bacteria. While its applications to potentially replace petroleum‐based plastics are severely limited due to its brittleness and ...

Effect of Radical Initiators on the Rheological Properties and Toughness of Poly(Lactic Acid)/Poly(3‐Hydroxybutyrate‐Co‐4‐Hydroxybutyrate) Blends

Polymer Engineering &Science, EarlyView.
Effect of mixing protocol on the size distribution of PHA domains in the PLA matrix. ABSTRACT In this study, poly(lactic acid) (PLA) and poly(3‐hydroxybutyrate‐co‐4‐hydroxybutyrate) [P(3HB‐4HB), a type of polyhydroxyalkanoate (PHA)], were melt‐blended at an 80/20 (wt/wt) ratio, and radical initiators were employed as reactive compatibilizers to enhance

Poly‐Ether‐Ether‐Ketone Melt Behavior in Fused Deposit Modeling Printing Moves

Polymer Engineering &Science, EarlyView.
A thin solidified layer forms at the print bed during FDM of PEEK, reducing the effective shear height and raising the effective shear rate above the nominal value. Surface defects emerge once the effective shear rate exceeds a critical value of approximately 750 s−1.
