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.
