Abstract: This article mainly introduced the synthesis methods of tetrazolyl polymer，including cycloaddition reaction method,free radical polymerization, and functional group reaction method. The application of tetrazolyl polymer in energetic material and membrane material was introduced. Tetrazolyl polymerhas advantage of high energy and low sensitivity in energetic material. Tetrazolyl polymer not only has conductivity but also can be applied in the environment at high temperature and without water.

Key words: Tetrazolyl polymer, Cycloaddition, Free radical polymerization, Binding agent, Proton exchange membrane
