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（CCl 4 ）率 20.13 g/g，重复 5 次进行吸油，依然保
持较高的吸油、保油效率。

Abstract: 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 CCl 4
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.
Key words: high oil absorption resin; oil absorption capacity; saturated oil absorption rate; centrifugal oil
retention rate; reuse ; series of acrylic chemicals
