Organocatalytic Ring-Opening Polymerization of <i>ε</i>-Caprolactone Using <i>bis</i>(<i>N</i>-(<i>N</i>′-butylimidazolium)alkane Dicationic Ionic Liquids as the Metal-Free Catalysts: Polymer Synthesis, Kinetics and DFT Mechanistic Study

Organocatalytic Ring-Opening Polymerization of <i>ε</i>-Caprolactone Using <i>bis</i>(<i>N</i>-(<i>N</i>′-butylimidazolium)alkane Dicationic Ionic Liquids as the Metal-Free Catalysts: Polymer Synthesis, Kinetics and DFT Mechanistic Study

In this work, we successfully synthesized high thermal stable 1,n-<i>bis</i>(<i>N</i>-(<i>N</i>′-butylimidazolium)alkane <i>bis</i>hexafluorophosphates (1,n-<i>bis</i>[Bim][PF<sub>6</sub>], n = 4, 6, 8, and 10) catalysts in 55–7...
