Emulsion templating of high internal phase emulsion was used to synthesize high oil-absorption resins with hexadecyl methacrylate and methyl methacrylate as monomers. Effects of cross-linking agent, emulsifier, initiator and porogen, polymerization temperature, polymerization time, the water/oil volume ratio, and the dosage of co-monomer on the properties of high oil-absorption resins were discussed. The optimum polymerization conditions for synthesis of high oil-absorbing resin were obtained. The highest oil absorbency in trichloromethane was 34 g/g. The oil absorbency of the resin remained constant after three times recovery.
