Curing behavior and Mechanical Properties of Polyurethane Propellant binder using Novel hydroxy-terminated polyether. |
| 초록 |
Novel synthetic routes were proposed for hydroxy-terminated Poly(EO-co-THF) by Cationic ring-opening copolymerization of tetrahydrofuran (THF) and ethylene oxide (EO). It was carried out using boron tirfluoride tetrahydrofuranate(BF3․ THF complex) as catalyst in the presence of 1,4-butanediol. The resultant products are well-defined linear polyether polyol. Polyurethane(TPU) were prepared using resultant polyether polyol with IPDI/N-100 as curing agent and TPB(triphenylbismuth)/MA(maleic anhydride) mixture as cure catalyst. Mechanical properties of Polyurethane prepared from poly(EO-co-THF) polyol were investigated and compared with polyurethane using commercial HTPE such as ATK HTPE. |
