【摘要】 本文用邻硝基乙苯为溶剂，替代工业上常用的剧毒的硝基苯对氯甲基化聚苯乙烯（简称氯球）进行付氏后交联反应，详细地研究了反应条件如：反应温度、催化剂的种类及用量等对树脂孔结构性能的影响。并在最佳反应条件下进行放大实验，合成出的后交联树脂的比表面为817m2／g，孔容为0．727ml／g，平均孔径为10．9nm。更多还原

【Abstract】 Nitrobenzene, the widely used solvent of Friedel-Crafts reaction in synthesizing hypercrosslinking copolymer, was substituted by 2-ethylnitrobenzene, a less toxic solvent.A series of experiments were carried out at various levels of factors (such as types and amounts of the catalyst, temperature and time for reaction and so on) to determine the optimum reaction conditions, under which the polystyrene with good adsorptive properties was yielded. The resins obtained in an enlarged scale reaction under such conditions have high surface area and pore volume of 817m2/g and 0.737ml/g, respectively.更多还原
