| 英文摘要 | To improve the miscibility and tensile strngth of the ABCPs material,we conducted a study in whcih maleimide end-capped polyurethane was prepared from the PU prepolymer and maleimide by reacting 4, 4'-diphenylmethane diisocyanate(MDI) with poly(tetramethylene oxide) (PTMO) , whose molecular weights were Mn=600 ∼ 700 (PA650), Mn=900 ∼ 1050 (PA1000) and Mn=1900 ∼ 2100 (PA2000). AB crosslinked polymers (ABCPs), synthesized from the PU prepolymer and the novolac resin, were studied. The study confirmed the occurrence of phase mixing. Fruther investigation through dynamic mechanical analysis (DMA) , differential scanning calorimetry (DSC) and transmission electron microscopy (TEM)revealed that the tensile strength and phase mixing were improved. |
