Two kinds of poly(glycidyl nitrate)(PGN) binders with molecular weight of about 3000 were synthesized via cationic polymerization using glycidyl nitrate(GN) with purity of more than 99.5% as raw material. Their structures were characterized by infrared spectroscopy(IR), nuclear magnetic resonance(NMR) and gel permeation chromatograph(GPC). The main properties of PGN were tested. The curing reaction of PGN with common isocyanates, polyaryl polymethylene isocyanate(PAPI), modified hexamethylene polyisocyanate(N-100), toluene diisocyanate(TDI), dicyclohexyl methane diisocyanate(HMDI) was studied. Results show that the curing reaction of PGN can performed rapidly with PAPI, N-100, TDI and HMDI etc. under the action of catalysts dibutyltin dilaurate(DBTDL) or triphenyl bismuth(TPB), and the cured samples have no obvious decrease in Shore A hardness after storeing at 60 ℃ for 60 days.
