摘　　要：用辉光放电电解等离子体引发悬浮聚合制备了丙烯酸酯类高吸收树脂聚(甲基丙烯酸丁酯-丙烯酸丁酯),并对放电参数、温度、水油比、单体比例、吸收选择性和吸收速率等进行了详细考察和讨论.用衰减全反射傅里叶变换红外光谱(ATR-FTIR)、热重分析(TGA)和扫描电镜(SEM)分别对产品的结构、热稳定性和表面形貌进行了表征.结果表明,在最佳合成条件下对四氯化碳、氯仿、二氯甲烷、苯、甲苯和二甲苯有较好的吸收,分别为128.1,134.4,145.8,95.6,71.3和69.2g.g-1.A highly oil-absorptive resin poly（butyl acrylate-butyl methacrylate） is prepared by suspension polymerization,which is initiated using glow-discharge electrolysis plasma.The structure of resin is characterized by means of attenuated total reflectance Fourier transform infrared spectroscopy（ATR-FTIR）,thermogravimetric analysis（TGA） and scanning electron microscopy（SEM）.The effects of the discharge voltage,discharge time,polymerization temperature,ratio of the water/oil and monomer ratio agent on the oil absorbency are examined and discussed in detail.In addition,kinetics of the oil absorption,oil absorption selectivity and oil-absorption rate are also studied.The results show that the oil absorbency is about 128.1,134.4,145.8,95.6,70.3 and 69.2 g·g-1 for carbon tetrachloride,chloroform,dichloromethane,benzene,toluene and xylene,respectively.
