Curing behavior and Mechanical properties of Polyurethane based on Well-defined Novel Poly(EO-co-THF) polyol |
| 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 polyetherpolyol. Polyurethane(TPU) were prepared using resultant polyetherpolyol with IPDI/N-100 as curing agent and TPB(triphenylbismuth)/MA(maleic anhydride) mixture as cure catalyst. Mechanical properties of TPU prepared from poly(EO-co-THF) polyol were investigated and compared with polyurethane using PEG and PTHF. |
