| Abstract: | The effects of plasticizer, curing agent, antioxidant as well as glycol structure on the thermooxidation of EO/THF copolyether urethane have been investigated by FT IR and NMR techniques. It is found that plasticizer dibutyl phthalate(DBP) has some stabilizing effect on the polyether urethane, but not on the degradation mechanism. Dibutyltin dilaurate(DBTDL) and triphenyl bismuth(TPB) show striking different behavior towords the thermooxidatin of polyurethane. Being plasticized with DBP, polyurethane with PEG as soft segments is more susceptible to thermooxidation than that with EO/THF copolymer, whereas the polyurethane plasticized with nitrate esters is less sensitive to thermooxidation. |
