摘　　要：以质量比为2:1的丙烯酸丁酯、甲基丙烯酸甲酯为单体,1.0%的过氧化苯甲酰(BPO)为引发剂,0.5%的二乙烯苯(DVB)为交联剂,采用悬浮聚合法合成了丙烯酸系吸油树脂(合成过程中加入一定量的苯乙烯)。研究了苯乙烯单体对吸油树脂微观结构的影响,分析了树脂的吸油性和缓释行为。结果表明:添加苯乙烯后,树脂颗粒表面有孔洞出现,硬度增加;苯乙烯用量为15%时,树脂对小分子CCl4的吸油性最优,同时树脂的热分解温度提高到373.3℃。A kind of oil absorption resin was synthesized by suspension polymerization, using butyl acrylate（BA） and methyl methacrylate（MMA） as monomer, benzoyl peroxide（BPO） as initiator and divinylbenzene（DVP） as cross linking agent. A certain amount of styrene was added during the synthesis process. The conditions are as follows： the mass ratio of BA to MMA is 2：1, the cross linking agent is 0.5% and the initiator is 1.0%. The effects of styrene monomer on the microstructure of oil absorption resin were studied. The oil absorption and sustainedrelease behavior of the resin were analyzed. The results show that： after adding styrene, the pores appear on the surface of the resin particles, and the hardness increases. When the content of styrene is 15%, the oil absorption of resin is the best, and the thermal decomposition temperature of the resin increases to 373.3℃.
