Direct Observation of Topologically Enhanced Interfacial Miscibility in Ring–Linear Polymers

Abstract Cyclic polymers, lacking chain ends, exhibit unique behavior when blended with linear analogues. In such cyclic/linear mixtures, cyclic polymers permit chain threading, wherein linear chains penetrate the ring-like structure, increasing entropy and enhancing interfacial...

Rational Design of Functional Bottlebrush Polymersfor Polylactide Blends with Improved Toughness and Antibacterial Performance

Abstract A series of bottlebrush polymers was rationally synthesized using norbornene-functionalized polylactide (NB-PLA), polycaprolactone (NB-PCL), and quaternized poly(2-(dimethylamino)ethyl methacrylate (NB-QPDM) via ring-opening metathesis polymerization (ROMP). These polyme...
