Abstract
In this paper, the ammonium dichromate and copper nitrate were used as raw materials to prepare the copper chromite, and nanocopper chromite as a catalyst was used to synthesize the monomer dioxanone in diethylene glycol dehydrogenation. Under the strict conditions of no water and no oxygen, the stannous octoate was selected to catalyze ring-opening polymerization of the dioxanone to prepare the polydioxanone. And dioxanone and its polymers were characterized with IR spectroscopy,1H NMR spectroscopy, thermogravimetric analysis (TG) and differential scanning calorimetry (DSC ) measurements.
