Ioannis Tzourtzouklis et al.
A new family of block copolymer electrolytes, where the "soft" block is synthesized via anionic ring opening copolymerization of ethylene oxide (EO) and glycidyl methyl ether (GME) and the "hard" block is glassy polystyrene (PS), overcomes ...

Intramolecular cyclization is a pervasive yet often ignored factor in step-growth polymerizations (SGPs), particularly under dilute conditions. While experimental studies have confirmed the significant impact of concentration on cyclization...
Vitrimeric Behavior Revealed by Fast Scanning Calorimetry in Branched Polyglycerol Networks Cross-Linked by Reversible Enamine Bonds [0.03%]

Kazuma Kumamoto et al.
Epoxy resins, which form highly cross-linked and permanent network structures by curing reactions between epoxy and amine compounds, are typically in a glassy state at room temperature. They are thus inherently brittle, a property that seve...
Impact of Stereocontrolled Polynorbornene Synthesis on Degradation Rate [0.03%]
