WebSep 1, 2012 · The coordination-insertion mechanism of the ROP allows the polyesters to be prepared under mild conditions from lactones of different ring-size , , . The … WebIn this purpose, the state-of-the-art coordination-insertion catalysts developed in the last decade will be evaluated. Some catalysts (e.g. Drent or Takeuchi catalysts) are reported to polymerize bulky and/or polar olefins that could efficiently synthesize bio-based polymers by coordination-insertion polymerization.
