Diclofenac orodispersible films by hot melt ram extrusion 3D printing [PDF]
, 2019 Background: Hot melt ram extrusion 3D printing was recently proposed to prepare small batches of orodispersible films (ODF), but the feasibility of loading thermosensitive drugs with low palatability has not been investigated.

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization
Macromolecular Rapid Communications, EarlyView.This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Polymer Composites, EarlyView.Masterbatch‐Assisted Fabrication of Polylactic Acid/Reduced Graphene Oxide Nanocomposites. ABSTRACT Polylactic acid (PLA) is a promising bio‐based polymer; nonetheless, its extensive application is still limited by poor fracture toughness, low thermal stability, and strong susceptibility to degradation induced by ultraviolet (UV) radiation.

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.
