A new polymeric copper catalyst (PVA@Cu Schiff base complex) was synthesized by
preparation of Schiff base ligand on the polyvinyl alcohol (PVA) framework in order to preparation of
cooper (II) complex and used for preparation of polytetrazole (PTZ) by polysalicylaldehyde (PSA) as a
precursor, hydroxylamine hydrochloride and azide salt via an easy and efficient one-pot, threecomponent
green method under mild conditions. PTZ and PVA@Cu Schiff base complex were
characterized with some methods include: FTIR, elemental analysis (CHNS), 1H NMR, UV-Vis, ICP
and TGA instruments. Eeasily recoverable, reusable property, good thermal stability and high excellent
yield for preparation of polytetrazole are some properties of the catalyst.
