摘　　要：采用悬浮聚合法合成了多孔性丙烯酸酯吸油树脂。研究结果表明,当体系中引入致孔剂时,溶剂萃取后的吸油树脂有着更好的油品吸收率,进一步证明了吸油率对树脂内部孔结构的依赖性。当单体用量27%(质量分数,以下同)、交联剂用量1.3%,引发剂用量0.7%,分散剂用量3%,水油比4∶1,所得树脂对苯、甲苯、二甲苯的吸油率分别达到18.082,9.831,9.064g·g-1;致孔剂乙酸乙酯的加入不仅使树脂对苯、甲苯、二甲苯的吸油率分别达到了30.174,18.233,16.333g·g-1,而且加快了吸油速度。Porous oil-absorbing resin was prepared by means of suspension polymerization. After melting agent extract absorb the oil resin to have the better oil article absorption rate by using porogenic agent, further certificate absorb the oil rate to the internal bore of resin the dependence of the structure. The results showed when BMA was 27% （wt）, MBAM was 1.3 % （ wt）, BPO was 0. 7% （wt） , PVA was 3 % （ wt）, O/W was 4： 1, the absorption of the resins to benzene, toluene and xylene were 18. 082, 9. 831, 9. 064 g·g^-1 ; and the absorption of the resins to benzene, toluene and xy- lene reached 30. 174, 18.233 and 16. 333 g ·g^-1, respectively by using ethyl acetate as porogenic agent.
