Rheological Characterization and Multi‐Regime Viscosity Modeling of Diluted Polyethylene Mixtures
Polymer Engineering &Science, EarlyView.This study maps the flow behavior of low‐density polyethylene in a recycling solvent from dilute solutions to entangled melts. By integrating time–concentration and time–temperature superposition, and coupling three complementary rheometry methods, a unified semiempirical model accurately predicts steady‐shear viscosity over nine decades of viscosity ...

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.

Catalytic Upcycling of Polyolefins
Chemical ReviewsThe large production volumes of commodity polyolefins (specifically, polyethylene, polypropylene, polystyrene, and poly(vinyl chloride)), in conjunction with their low unit values and multitude of short-term uses, have resulted in a significant and pressing waste management challenge. Only a small fraction of these polyolefins is currently mechanically

Performance Evaluation of Compression‐Molded Recycled Mixed Plastic Fractions From Light Packaging
Polymer Engineering &Science, EarlyView.Mixed HDPE/PP bottle‐cap waste was successfully processed through closed‐loop mechanical recycling. The recycled blends maintained stable thermal, rheological, and mechanical performance over multiple cycles, demonstrating the feasibility of valorizing heterogeneous polyolefin waste without advanced polymer separation.
