以聚乙烯醇(PVA)为分散剂、二乙烯基苯(DVB)为交联剂、过氧化苯甲酰(BPO)为引发剂、乙酸乙酯(EA)为致孔剂,选用长链单体甲基丙烯酸十八烷基酯(SMA)和短链单体甲基丙烯酸异丁酯为原料以悬浮聚合法成功合成了一种丙烯酸酯二元共聚高吸油树脂。通过红外(FT-IR)、扫描电子显微镜(SEM)和热重(TG)分析法对树脂进行表征,并考察了各因素对4种待测油品吸油性能的影响。结果表明,该树脂对三氯甲烷、甲苯、环己烷、柴油的饱和吸油率分别为20.69、13.87、12.05、10.93 g/g。树脂的最佳合成条件为:w(SMA)80%、w(BPO)1%、w(DVB)0.5%、w(PVA)1%、w(EA)50%、W/O为5∶1。

A kind of binary acrylate copolymers resin is successfully synthesized through suspension polymerization method from octadecyl methacrylate (SMA),a long chain monomer,and isobutyl methacrylate,a short chain monomer,using polyvinyl alcohol (PVA) as dispersant,divinylbenzene (DVB) as crosslinking agent,dibenzoyl peroxide (BPO) as initiator,and ethyl acetate (EA) as pore-forming agent.The resulted resin is characterized by infrared spectroscopy (FT-IR),scanning electron microscopy (SEM) and thermogravimetry (TG).The effect of various factors on the absorption properties of the resin to four kinds of testing oils is investigated.The results show that the saturated absorption rates of the resin to trichloromethane,toluene,cyclohexane and diesel are 20.69,13.87,12.05 and 10.93 g·g^-1,respectively.The optimum synthetic conditions for the resin are as follows:the mass ratio between water and oil is 5:1,the mass fractions of SMA,BPO,DVB,PVA,EA are 80%,1%,0.5%,1% and 50%,respectively.
