摘　　要：采用悬浮聚合的方法,以丙烯酸丁酯(BA)和甲基丙烯酸甲酯(MMA)为单体、过氧化二苯甲酰(BPO)为引发剂、邻苯二甲酸二烯丙酯(DAP)为交联剂、聚乙烯吡咯烷酮(PVP)为分散剂,合成了丙烯酸酯类高吸油性树脂(POA树脂)。采用FTIR对POA树脂进行了表征,并在不同油品中考察了树脂的饱和吸油率、离心保油率。结果表明:两种单体悬浮共聚合成了POA树脂,对多种油品均具有一定的吸收性,但对于不同种类油品的吸收能力并不相同,其饱和吸油率由大到小排序依次为:卤代烃>芳香烃>丙酮>脂肪族烃及环烷烃,进一步的实验发现树脂的饱和吸油率越高,其离心保油率越低。通过TG和重复吸油测试证明了合成的POA树脂在较高的环境温度下能够稳定使用,并能保持较高的饱和吸油(CCl4)率20.13g/g,重复5次进行吸油,依然保持较高的吸油、保油效率。A polyacrylate high oil absorption resin(POA resin) was prepared by suspension polymerization using butyl acrylate(BA) and methyl methacrylate(MMA) as monomers, dibenzoyl peroxide(BPO) as evocating agent, diallyl phthalate(DAP) as crosslinking agent, polyvinyl pyrrolidone(PVP) as dispersing agent. The resulting POA resin was characterized by FTIR. The saturated oil absorption rate and centrifugal oil retention rate of PAO resin were studied in different oil products. The results showed that POA resin was successfully synthesized and had certain absorbability to various oil products, but the oil absorption capacity of different kinds of oil was not the same. The order of saturated oil absorption rate was halogenated hydrocarbon > aromatic hydrocarbon > acetone > aliphatic hydrocarbon and cycloalkane. Further experiments found the higher the saturated oil absorption rate of resin, the lower the centrifugal oil retention rate. Thermogravimetric analysis(TG) and repeat oil absorption test proved that the synthesized POA resin could be used stably at high temperature and keep a high saturated oil absorption rate for CCl4 about 20.13 g/g. Even if it was repeated 5 times for oil absorption, PAO resin still could maintain a high oil absorption and oil retention rate.
