| 摘 要： | Three-component IPNs were synthesized from polyurethane/poly (methyl acrylate aminoethyl methacrylate)/epoxy resin [PU/P(MADMA)/EP] by simultaneous synthesis interpenetrating polymer networks method(SINs) and sequential synthesis interpenetrating polymer networks method (STPNs). Comparing the effect of the two synthesis methods on the morphology and mechanical properties of three-component IPNs, it was found that the compatibility of three-component IPNs depends on the component ratios and interpenetrating formation , the different synthesis methods make the entanglement and interpenetrating between networks changed. The tensile strength of SIPNs is bigger than that of SINs, while the elongation at break of SINs is bigger than that of SIPNs. It is feasible to use stepwise staining method to observe the morphology change.
