This work reports the relationship between monomer composition of typical acrylate copolymers and their oil absorption behaviors, considering the steric effects of isobornyl methacrylate (IBOMA) or reactive silica nanoparticles. With a molar ratio of stearyl acrylate (SA): butyl acrylate (BA): IBOMA = 1:1.2:0.3, the random copolymers exhibited absorbency of more than 30 mL/g for benzene, xylene, and other common fuel oils. The copolymers of SA and BA synthesized in the presence of 2% reactive silica nanoparticles (R-SiO2) showed further improvement in oil absorbency, reaching 39.5 mL/g, 43.6 mL/g, and 40.7 mL/g for benzene, xylene, and CCl4, respectively. Compared to copolymers of SA and BA, copolymers formed using IBOMA or R-SiO2 mainly hindered the diffusion of viscous oils such as kerosene or diesel, leading to decrease in absorption rate. All the prepared copolymers exhibited oil retention up to 99% for gasoline, kerosene, and CCl4 after saturation of absorption, after centrifugation at 3000 rpm for 5 min, which is attractive for practical applications.
