Influence of Chain Extender on The Thermal, Rheological, and Supercritical Foaming Behavior of Polyamide‐12

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Chain extender concentration strongly influence the batch foaming behavior of PA 12 under supercritical CO2. Increasing CE content improves melt stability, raises viscosity and broadens the foaming window, enabling fine, uniform cellular structures. The optimal 0.5 wt.% CE yields the highest nucleation density and lowest foam density, about 0.06–0.09 g/

Synthesis and Recycling‐on‐Demand of Novel Bio‐Based Poly(Ester‐co‐Acetal)s Designed for Circularity

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Fully bio‐based oligoesters with defined terminal groups are designed and synthesized utilizing solvent‐free melt polycondensation. An effective chain extension reaction transforms oligomers into semi‐crystalline poly(ester‐co‐acetal)s that can be hot‐pressed into foils.

Quantification of Homopolymer Impurities in Structured Acrylate Copolymers Produced by High‐Temperature Semi‐Batch Radical Polymerization

Macromolecular Reaction Engineering, Volume 20, Issue 4, August 2026.
Isobornyl acrylate macromonomer solutions are synthesized via high‐temperature radical polymerization using a starved‐feed semi‐batch operating policy. Through sequential feeding, the macromonomer solution functions as an addition‐fragmentation agent, facilitating the production of blocky and comb acrylate copolymers.

Suppressing Polysulfide Shuttle and Boosting Reaction Kinetics via UiO‐66‐SH‐Functionalized Separators for Lithium–Sulfur Batteries

Small Science, Volume 6, Issue 8, August 2026.
This work demonstrates a UiO‐66‐SH‐functionalized separator that boosts Li+ transport, thermal stability, polysulfide anchoring, and sulfur redox kinetics in Li–S batteries. As a result, the cell delivers an initial capacity of 821.3 mAh g−1 at 1 C and retains 521 mAh g−1 after 500 cycles.

Plastics and Bioplastics End of Life: A Biocatalytic Perspective

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
Biocatalysis links selected conventional plastics and bioplastics to biological routes for polymer transformation, product recovery and end‐of‐life management. Enzymes and microbes enable depolymerisation, upcycling and recovery of monomers, platform chemicals and new materials.
