摘要: 在苯乙烯-二乙烯苯共聚体系中加入甲基丙烯酸甲酯、丙烯酸甲酯、甲基丙烯酸、丙烯腈和乙酸烯丙酯等第三单体,对吸附树脂表面进行修饰,用物理技术和化学方法表征了合成树脂的结构,测定了它们对甜菊甙的吸附量。结果表明,第三单体的极性和用量等因素对树脂的孔结构和吸附量有较大的影响。

Abstract: This paper studied the modification of macroporous adsorbents by adding some polar monomer, such as methyl methacrylate, methyacrylate, methyacrylaic acid, acrylonitrile or allyl acetate, in the copolymerization of styrene and divinylbenzene.The structure of adsorbents modified was characterized by means of physical technology and chemical methods,and the adsorption properties for stevioside were determined.The results of experiments show that the polarities of these resins have an important influence on their physical structure and adsorptive capacity.

Key words: Adsorbent, Polystyrene resin, Stevioside
