During the last decades, there have been many efforts intend to find renewable resources that can alternate the oil-based materials due to the depletion of petroleum reservoirs and environmental issue. Among polymetric materials, epoxy resins are an important class of thermosetting polymers due to there excellent mechanical properties and thermal resistance, there fore they have many applications on adhesives, coatings, electronic component and so on. In this work, levulinic acid was used as a renewable resource to prepare an epoxy monormer and phosphorus containing functional group was incorporated to enhance its flame resistance. The new flame retardant epoxy resin was synthesized via five-step reaction and its structure was characterized by 1H-NMR, 13C-NMR and 31P-NMR. |
