Abstract:
1. A method of preparing a phosphazene polymer, wherein the phosphazene polymer is prepared by heating the curable cyclic phophazene compound represented by Formula (I) below, by dissolving the curable cyclic phosphazene compound in an organic solvent, mixing AIBN(azobisisobutyronitrile) therewith and then heating the mixture, by dissolving the curable cyclic phosphazene compound in an organic solvent, mixing cupric acetate (Cu(II) acetate) therewith as a catalyst and then heating the mixture, or by mixing the curable cyclic phosphazene compound with a photoinitiator (2,2-dimethoxy- 2-phenyl acetophenone) and then photopolymerizing the mixture using a high-pressure mercury lamp: (I) wherein n is 3, R R R
