Synthesis of Energetic Polynorbornene with Pendant Bis-Azidoacetyloxymethyl Groups (PNBAA)

Abstract

A novel energetic polynorbornene with pendant bisazidoacetyloxymethyl (named PNBAA) was designed, by combining intrisicly energetic property, potential good mechanical property, compability with plasticizer and odourless polynorbornene in one polymer. A green synthesis of PNBAA was achieved starting from easily available materials, by using solvent-free Diels-Alder reaction, chloroacetylation of norbornene dimethanol in water, solvent-free ring opening metathesis polymerization (ROMP), azidation in aqueous 3-pentanone and tandem ROMP and azidation in one pot. In addition, Nuclear Magnetic Resonance (NMR) technique was utilized to investigate the key ROMP and azidation steps in-situ. PNBAA as an energetic polymer was demonstrated by measuring its TG-IR, DSC and mechanical sensitivity. The strategy reported in this paper will lead to the general green synthesis of diverse energetic polymers in the future.
