Abstract
This article reported a novel type of lipophilic polyelectrolyte resin with high oil absorbency and mechanical properties, which was suitable to use, store, and recycle. A certain amount of weakly coordinating ions was introduced in a suitable network structure of copolymer resin of styrene/butyl methacrylate/stearyl methacrylate by chloromethylation reaction, quaternization reaction, and anion exchange reaction. The structure and particle morphology of resin were characterized by Fourier transform infrared spectrometry and scanning electron microscopy, respectively. Research on oil absorption test has revealed that lipophilic polyelectrolyte resin had higher oil absorbency, faster oil-adsorbing rate, and better reusability compared with non-ionic oil absorption resin. Meanwhile, the effect of the content of ionic groups on the oil absorbency of the lipophilic polyelectrolyte resin was also investigated. The results showed that the maximum of oil absorbency of the resin to the carbon tetrachloride was 37.86 g/g when the content of ionic groups was 4.54 wt%.
