Existing adsorption materials with drawbacks in the weak organic solvents/oil retention ability, slow adsorption speed and low adsorption capacity for alkanes still hardly meet demands of the application field, especially in emergencies. The copolymerization of the long‐chain alkenes, 1‐octene, with isoprene was designed in this paper to synthesize an adsorption resin (PIOT), instead of acrylate monomers reported in the literature. And trimethylolpropane triacrylate was designed as a crosslinking agent. Results show that the PIOT grows in the form of powders, which are the loose accumulation of nanoflakes with a diameter of about 47.89 ± 11.06 nm. In view of the chain structure and morphology of the PIOT, it can quickly reach the maximum adsorption within 10 s along with a high adsorption capacity for various solvents and kerosene. Even for hexane, the adsorption capacity of the PIOT increases by 345.2% compared with the reported adsorption resin. The oil retention rate of PIOT can be maintained at 86 ± 6% after centrifugation at 1000–3000 rpm for 5–25 min. Compared with commercial activated carbon, the PIOT has outstanding advantages in recycling property and oil retention rate and compared with the reported acrylate adsorption resin, the PIOT has made a great breakthrough in adsorption capacity for alkanes.
