摘要
Nitrato\|terminated polyalkylene glycols were synthesized from nitrating glycols with nitric acid and sulfuric acid in methylene chloride. Then azido\|terminated polyalkylene glycols were prepared by a nucleophilic reaction of the nitrato\|terminated polyalkylene glycols with sodium azide in different phase transfer catalytic conditions. All synthesized polymers were characterized by \{\}\+1H\|MNR, FT\|IR, GPC and elemental analysis.
