摘要： 使用Lewis酸催化剂, 用自制的氯甲基化试剂1,4-二氯甲氧基丁烷(BCMB), 在室温下对聚苯乙烯交联微球(白球)进行氯甲基化反应, 制得了氯含量接近17%的氯甲基化聚苯乙烯交联微球(氯球); 通过红外光谱法与佛尔哈德分析法表征了产物的化学结构与组成; 考察了各种因素对氯甲基化反应过程的影响规律. 结果表明, 各种因素对白球氯甲基化过程的影响表现在两个方面: (1) 影响白球的氯甲基化程度; (2) 抑制或促进分子链之间通过Friedel-Crafts反应进一步交联, 影响微球的强度.

Abstract: The chloromethylation reaction of crosslinking polystyrene microspheres(white-sphere) was performed at room temperature by using self-made chloromethylation reagent, 1,4-bis(chloromethoxy)butane(BCMB), as the chloromethylation reagent and adopting Lewis acid catalysts, and the chloromethylated crosslinking polystyrene microspheres(chloro-sphere) with a chlorine content of 17% was obtained. The chemical structure and composition of the product were characterized by FTIR and Volhard methods, and the effects of various factors on the chloromethylation reaction were mainly examined. Various factors not only affect the chloromethylation degree of the white sphere, but also inhibit or accelerate the Friedel-Crafts crosslinking reaction between macromolecular chains and affect the strength of the chloro-sphere.

Key words: Polystyrene, 1,4-Bis(chloromethoxy)butane, Chloromethylated crosslinking polystyrene microsphere, Chloromethylation
