Recyclability of Polystyrene Bead Foams: Degradation Behavior over 10 Extrusion Cycles

Polymer Engineering &Science, Volume 66, Issue 3, Page 1711-1722, March 2026.
This study investigates the multi‐cycle recycling of expanded polystyrene bead foam blended with virgin material. Material degradation is monitored by MFI, GPC, and mechanical testing. The results demonstrate that long‐term recyclability is feasible without progressive property loss, and that secondary high‐shear steps such as extrusion and pelletizing

Synthetic Cells on Demand: From Molecular Stimuli to Cellular Functions

ChemSystemsChem, Volume 8, Issue 2, March 2026.
ABSTRACT Synthetic cells constructed via bottom‐up approaches using lipid or polymer vesicles have become essential tools for mimicking cellular functions and studying synthetic biological systems. These vesicles can undergo morphological changes and trigger internal reactions in response to external stimuli, such as osmotic pressure, temperature, pH ...

Olefin Polymerizations Oriented by Rational Designs of Group‐13 Compounds

The Chemical Record, Volume 26, Issue 3, March 2026.
In coordination olefin polymerization chemistry, boron and aluminum compounds play important roles in both catalyst components and monomers. This personal account introduces our recent progress on the development of catalyst systems featured by the design of group‐13 counteranions, as well as the application of boronic acid‐crosslinked polyolefins to ...

"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.
