Shibuya, Yoshiki published the artcileBrush-First ROMP of poly(ethylene oxide) macromonomers of varied length: impact of polymer architecture on thermal behavior and li+ conductivity, Quality Control of 23783-42-8, the main research area is ROMP polyoxyethylene macromonomer polynorbornene architecture thermal ionic conductivity; polymer electrolyte solid battery polyoxyalkylene polyalkenamer bottlebrush; ring opening metathesis polymerization polyethylene oxide macromonomer norbornene.
The properties of polymeric materials are dictated not only by their composition but also by their mol. architecture. Here, by employing brush-first ring-opening metathesis polymerization (ROMP), norbornene-terminated poly(ethylene oxide) (PEO) macromonomers (MM-n, linear architecture), bottlebrush polymers (Brush-n, comb architecture), and brush-arm star polymers (BASP-n, star architecture), where n indicates the average d.p. (DP) of PEO, are synthesized. The impact of architecture on the thermal properties and Li+ conductivities for this series of PEO architectures is investigated. Notably, in polymers bearing PEO with the highest d.p., irresp. of differences in architecture and mol. weight (∼100-fold differences), electrolytes with lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) as an Li+ source exhibit normalized ionic conductivities (σn) within only 4.9 times difference (σn = 29.8 × 10-5 S cm-1 for MM-45 and σn = 6.07 × 10-5 S cm-1 for BASP-45) at a concentration of Li+ r = [Li+]/[EO] = 1/12 at 50 °C. © 2018 Wiley Periodicals, Inc.J.
