• Hydrogen phosphates: Self initiated organocatalysts for the controlled ring-opening polymerization of cyclic esters
  作者：Payal Malik、Debashis Chakraborty

  DOI：10.1016/j.ica.2013.02.006

  日期：2013.5

  A series of arylhydrogenphosphates and aryldihydrogenphosphates was synthesized and characterized using spectroscopic methods and single crystal X-ray diffraction. These compounds were assessed as catalysts towards the ring-opening polymerization and proved to be potent organocatalysts for the ring-opening polymerization of cyclic esters. The bulk polymerizations were performed in the absence of external initiator. The polymerization proceeds in a controlled fashion which leads to well defined polyesters with narrow molecular weight distributions. In the post polymerization experiments, kinetics, mechanism and monomer concentration effects were investigated. The kinetic results have confirmed the pseudo-living character of the polymerizations and mechanistic studies suggest that the polymerization operates through a cationic mechanism.
