摘要：
Compressible and elastic porous oil absorbent resins of P(BMA- co- MMA) were synthesized by high internal emulsion template method using butyl methacrylate (BMA) and methyl methacrylate (MMA) as monomer, divinylbenzene (DVB) as crosslinking agent, sorbitan monooleate (Span 80) as emulsifier, and 2, 2'- azobis(2, 4- dimethyl) valeronitrile (ABVN) as initiator. The structure of porous P(BMA- co- MMA) resins was characterized by FT- IR and SEM, and the mechanical properties of porous resins were tested. The effects of the monomer ratio and surfactant amount on oil absorption performance of the porous resins were investigated, and the oil-water separation performance of porous resins was evaluated. The results show that the porous P(BMA- co- MMA) resin display the optimal oil absorption performance when the mass ratio of BMA and MMA is 7:3 and the amount of emulsifier accounts for 16.67 % of the mass of monomers. The maximum adsorption capacity of the porous resin towards dichloromethane is as high as 51.95 g/g with the oil retention rate reaching above 93%. In addition, the porous resin exhibits a high hydrophobicity with the water contact angle (WCA) of 143° and superoleophilicity with the oil contact angle of 0°. The porous resin completely absorbs toluene in water within 20 s, which is expected to be applied in oil-water separation treatment. © 2022, Editorial Board of Polymer Materials Science & Engineering.
