Polydodecylmethacrylate-2-ethyl hexyl acrylate resin was synthesized by means of microwave irradiation. Morphologies and textural properties of the synthesized resins were characterized by Scanning Electron Microscopy (SEM). The adsorption of oil fume on the resins was measured. The effects of monomer ratio, initiator dose, dispersant dose, and cross-linker dose as well as synthesis reaction temperature on the synthesized resin adsorption of oil fume were investigated. Results showed that when the monomer ratio (2-ethyl hexyl acrylate/dodecylmethacrylate), initiator dose, dispersant, and cross-linking agent dose were 3:7, 1%, 1.5%, and 0.6%, respectively, the synthesized resins had a developed porous structure and its maximum adsorbed amount of oil fume was available. In comparison with synthesis method of traditional water-bath heating, the use of microwave irradiation can improve the conversion efficiency of synthesis reaction, and greatly shorten synthesis reaction time from 6 h to 2 h. The WR resin synthesized by using microwave irradiation has higher adsorption capacity of oil fume compared to the NR resin synthesized by traditional water-bath heating method.
