摘要
A highly absorptive resin poly （butyl methacrylate （BMA）-co-butyl acrylate （BA）） was prepared by emulsion polymerization, which was initiated by glow discharge electrolysis plasma （GDEP）. The effects of discharge voltage, discharge time, monomer ratio and the amounts of cross- linking agent were examined and discussed in detaiI. The chemical structure of the obtained resin was characterized by means of attenuated total reflectance Fourier transform infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy. The optimal conditions were ob- tained as： discharge voltage was 600 V, discharge time was 8 min, the ratios of BMA：BA being 2：1 for chloroform and 3：1 for xylene, with 2% N, N＇-methylenebis. Under optimal conditions, the oil absorbency was 70 g/g for chloroform and 46 g/g for xylene. Moreover, the absorptive dynamical behavior of the resulting resin was also investigated.
