Sample TextNovel phosphazene cyclomatrix network polymers were synthesized via nucleophilic displacement of activated nitro groups of tri(4-nitrophenoxy)tri(phenoxy)cy clotriphosphazene and hexa(p-nitrophenoxy) cyclotriphosphazene with the hydroxyls of bisphenol A. Both the monomers and polymers were characterized by Fourier transform infrared (FTIR) and H-NMR spectroscopy, and their structures were identified. ![]() ![]() ![]() ![]() ![]() ![]() [ Last edited by wellok101 on 2008-3-13 at 14:34 ] |
