摘　　要：采用悬浮聚合法,以水为分散相,甲基丙烯酸十二酯(DMA)为长链单体,苯乙烯(St)为短链单体,二乙烯基苯(DVB)为交联剂,过氧化苯甲酰(BPO)为引发剂,合成了低交联度的高吸油性树脂,研究了单体配比、引发剂用量、交联剂用量对树脂性能的影响,测定了树脂的DSC-TG曲线,以及树脂吸油前后的SEM形貌表征。结果表明:合成的高吸油性树脂吸油效果较为理想,其中对甲苯的吸收倍率可达到7.03g/g,煤油的吸收倍率可达到6.59g/g,航空煤油的吸收倍率可达到6.12g/g,并且树脂具有良好的热稳定性。The high oil absorbing resin consisting of dodecyl methacrylate （DMA） and styrene （St） was prepared by suspension polymerization. In the polymerizing reaction system, the two monomers were polymerized by using benzoyl peroxide （BPO） as initiator, divinyl benzene （DVB） as cross-linker and water as dispersal phase. The effects of the ratio of the monomers, initiator content and cross-linker content on conversion and properties of the copolymer were studied. Structure and performance of the resins were investigated by means of DSC-TG, SEM. The results showed that the resin had good oil absorption capacity and heat-resistant performance. The absorption capacities of toluene, kerosene and jet fuel were 7.03 g/g, 6.59 g/g and 6.12 g/g, respectively.
