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

Synthesis and Characterization of an Azido Nitrofurazanyl Ether: An Energy‐Rich Heterocyclic Plasticizer With a Low Glass Transition Temperature

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1365-1374, August 2026.
ABSTRACT We report on the synthesis and characterization of 3‐(2‐(2‐azidoethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG2N3), which is a liquid nitrofurazanyl ether that was designed to be an energy‐rich plasticizer for glycidyl azide polymer (GAP)‐ and nitrocellulose (NC)‐based formulations.

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1224-1234, August 2026.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.

"Synthesis and characterization of high vinyl star-shaped liquid polybutadiene"

Hecheng xiangjiao gongye
Using cyclohexane and n-hexane as solvents, butadiene as monomer, and n-butyllithium as initiator, star-shaped liquid polybutadiene was synthesized via arm-first method with di-tetrahydrofurfuryl propane (DTHFP) as structure regulator.

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

A theory for the thermal conductivity of highly viscous chain-like polymer melts [PDF]

AIP Advances
Polymers play a key role in many modern electronic applications. Conventional pure (unfilled) polymers, with inherently low thermal conductivity (6×106Da) of polyethylene, polyethylene oxide, and polybutadiene may exhibit giant thermal conductivity ...
