Facile Approach to Modulating Stereochemistry in Ring‐Opening Metathesis Polymerization of Cyclooctadiene

Journal of Polymer Science, EarlyView.
The stereochemistry of polybutadiene made by ring‐opening metathesis polymerization (ROMP) evolves both during and after polymerization, as secondary metathesis shifts cis‐rich kinetic products toward trans‐rich equilibrium compositions. By tuning catalyst identity, additives, temperature, and reaction time, polybutadienes with 28%–80% trans content ...

Screening Surface Modifications to Benzene to Improve Solubility in Hydroxyl‐Terminated Polybutadiene (HTPB)—A DFT Demonstration

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The objective of this paper is to demonstrate the advantage of computationally pre‐screening surface‐modifying material candidates, using density functional theory (DFT), to inform experimental synthesis and formulation efforts. This demonstration focuses on improving the solubility of benzene‐based materials in hydroxyl‐terminated ...

Field‐Cycling NMR Relaxometry in Tire Elastomer Science

Magnetic Resonance in Chemistry, Volume 64, Issue 9, Page 801-820, September 2026.
Field‐cycling NMR relaxometry has established as an ideal tool to investigate multiscale polymer dynamics. Here, we review and discuss applications on elastomers and elastomer compounds of interest for the tire industry to obtain information on segmental dynamics and on polymer dynamics over different regimes as a function of chain length in polymer ...

Study of the Biodegradation Properties of Amorphous Blends of Poly(Lactic Acid) and Poly(3‐Hydroxybutyrate‐co‐4‐Hydroxybutyrate) Foamed With Supercritical CO2

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Supercritical CO2 foaming of fully amorphous PLA/PHA blends produced low‐density closed‐cell foams with fine cellular morphology. Blending with PHA enhanced biodegradation under simulated home‐composting conditions, achieving up to 84% mass loss after 4 months, whereas marine degradation remained limited and was mainly restricted to the PHA component ...

Effect of recycling on mechanical and physical properties of polycarbonate/acrylonitrile–butadiene–styrene/poly(methyl methacrylate) (PC/ABS/PMMA) blends

Polymer International, Volume 75, Issue 8, Page 748-758, August 2026.
The 100% recycling of optimal polycarbonate/acrylonitrile–butadiene–styrene/poly(methyl methacrylate) (PC/ABS/PMMA) blends, identified through the mixture design, over multiple successive cycles provides valuable insights into their life cycle. Subsequently, chemical, rheological, thermal and mechanical characterizations will be carried out to evaluate

Assessment of Microplastic Ingestion in Commercial Marine Fish From Cities of Sibu and Kuching, Eastern Sarawak, Malaysia

Environmental Quality Management, Volume 36, Issue 2, August 2026.
ABSTRACT Microplastic (MP) pollution is an ever‐growing issue in the marine ecosystem around the world. However, the study on MP pollution in marine fish remains limited, particularly those conducted in Eastern Sarawak, Malaysia. Hence, this study investigated the occurrence of MP on the marine fish, collected from local fish market in the city of Sibu
