Di-, Tri- and Tetrafunctional Poly(ε-caprolactone)s by Bi(OAc)3-Catalyzed Ring-Opening Polymerizations of ε-Caprolactone

ε-Caprolactone was polymerized in bulk at 150 °C with either tetra(ethylene glycol) (TEG), 1,1,1-tris(hydroxymethyl)propane, or Pentaerythritol as initiator and bismuth(III) acetate Bi(OAc)3 as catalyst. The reaction times needed for nearly quantitative conversion were determined. The polylactones i...
