The design of new energetic molecules is based on compounds exhibiting a high density and an elevated heat of formation. These fundamental properties, achieved through the presence of numerous nitrogen atoms. The syntheses of two new energetic polymers containing moieties of tetrazole and diaminotriazine have been carried out in this work. The 4-chloromethyl styrene (CMS) was polymerized by free radical polymerization (FRP) method at 80 ºC using α,α-azobis(isobutyronitrile) (AIBN) as an initiator. The PCMS was transformed to PAS by Kornblum's oxidation of methylene chlorides to aldehyde groups in one step. Aldehyde groups of PAS were produced tetrazole and triazine rings in one-pot reaction. The polymers, obtained in quantitative yields, were characterized by FT-IR and 1H NMR spectroscopy and TGA studies. Thermal properties nitrogen-rich polymers show that explosive thermal degradation takes place at around 230 ° C.
