Abstract: Two kinds of amino resins were prepared with chloroacetylated polystyrene （PS-Acyl-Cl） as carrier to replace chloromethyl polystyrene by reacting with ethylene diamine （EDA） and hexamethylene diamine （HMD）. Such influence factors as reaction time，temperature，molar ratio of raw materials，and solvents were discussed. Under the optimum conditions，the loading amount of ethylene diamine and hexamethylene diamine on the resin could be up to 1.60 mmol/g and 2.6 mmol/g，respectively. While，the loading amount of hexamethylene diamine was apparently higher than that of ethylene diamine under the same conditions. In this method，the drawbacks of preparing chloromethylated polystyrene resin were avoided，and side reactions，such as secondary cross-linking and multi-substitution could be eliminated. As active intermediates，the amino resins can be derivatized to obtain many functional media.

摘要： 以氯乙酰化聚苯乙烯（PS-Acyl-Cl）代替氯甲基化聚苯乙烯作为载体，引入乙二胺（EDA）和己二胺（HMD）得到2种胺基树脂。考察了反应时间、油浴温度、物料比、溶剂体系等对胺化反应的影响，在最佳反应条件下，乙二胺和己二胺树脂的担载量分别达到1.60 mmol/g和2.6 mmol/g。将2种胺基树脂进行比较：在相同条件下，制备的己二胺树脂的担载量明显高于乙二胺树脂。该方法避免了氯甲基化法存在的弊端，并消除了烷基化引起的二次交联及多取代等副反应。制备的胺基树脂可以作为一个活性中间体，进一步衍生化制备多种功能介质。
