An acrylate high oil-absorbing resin was prepared by suspension polymerization of using butyl acrylate (BA) and methyl methacrylate (MMA) as monomers, dibenzoyl peroxide (BPO) as a evocating agent, diallyl phthalate (DAP) as a crosslinking agent, and polyvinyl pyrrolidone (PVP) as a dispersing agent .AOA resin was characterized by FTIR, and the saturated Oil absorption rate, and centrifugal oil retention rate of the resin were studied in different kinds of oil. The results show that AOA resin which is composed of two monomers by suspension polymerization can absorb all kinds of oil strongly, but the oil absorption capacity of different kinds of oil is not the same. The order of saturated oil absorption rate is halogenated hydrocarbon > aromatic hydrocarbon > acetone > aliphatic group and cycloalkane. It is proved that the synthesized AOA resin can be used stably at high temperature and keep a high saturated oil absorption rate repeatedly by thermogravimetric analysis（TG）and repetitive experiment environment-friendly and efficiently.
