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.
