Through suspension polymerization, the influences of different crosslinking agent, initiator, disperser and reaction temperature on oil absorption rate of cetane methacrylate highly oil absorptive resin were studied. The oil absorption ability of the resin for different oil was investigated. The results show the oil absorption capacity of synthesized resins is good with crosslinker divinylbenzene(DVB), initiator benzoyl peroxide(BPO) and disperser polyvinyl alcohol(PVA). Suitable process conditions were: crosslinker DVB is 1.0%, initiator BP is 1.2%, disperser PVA is 0.8%, reaction temperature is 70 degrees C, and oil absorptive power of obtained resin is about 36.6g.g(-1) for CCl4.
