摘　　要：以邻氯苯乙烯和二乙烯基苯为原料制备了邻氟苯乙烯-二乙烯基苯强酸性阳离子交换树脂，考察了水油比、分散剂、助分散剂等因素对合成树脂的影响。研究表明，该树脂的合成最佳工艺条件为：水油比3：1-4：1，聚乙烯醇与明胶分别为水相质量的0．1％和1．0％，助分散剂为水相质量的0．5％，电解质为水相质量的10％，在40-80℃的成球关键期控制升温速率为20℃/h，在80～110℃以发烟硫酸辅助磺化，得到交换量大于4mmol／g的树脂，优化了该树脂的合成工艺。o-chlorostyrene and divinylbenzene occurred suspension copolymerization could obtain high quality copolymer beads. The effects of water-oil ratio, dispersants, assist dispersants and other factors were studied. The optimum reaction conditions： water-oil ratio was from 3： 1 to 4： 1; polyvinyl alcohol, gelatin, secondary dispersants and electrolyte were respectively 0.1%, 1.0%, 0.5% and 10% ratio of water, the heating rate should be controlled at 20℃/h during the critical period of 40-80℃. Beads sulfonated at 80-110℃ by oleum could be made into strongly acidic cation exchange resin. The exchange capacity was more than 4mmol/g and the synthesis technology of resin has been optimized.
