摘要:: 以氯甲基化聚苯乙烯–二乙烯苯交联微球(PS,氯球)作为出发物质,分别以乙二胺(EDA)、乙醇胺(ETA)、乙二醇(EG)作为连接臂,经过接枝反应制备改性的聚苯乙烯微球,再使改性微球与三聚氯氰反应,经取代得到聚苯乙烯三聚氯氰树脂.用红外光谱仪对所制备的3种不同连接臂的三聚氯氰(CNC)树脂进行了表征及分析,结果表明,连接臂中氨基的存在更有利于改性氯球,也有利于三聚氯氰负载.从对目的物三聚氯氰的接枝量分析,经EDA改性的氯球对三聚氯氰的负载优于ETA和EG,其负载三聚氯氰反应的增重率高达28.1% ,三聚氯氰树脂担载量高达1.48 mmol/g,氯含量达到5.9% .制备得到的三聚氯氰树脂可以作为催化剂或者活性中间体,进一步制备多种功能介质.

Abstract:: Using the chloro-methylated polystyrene-divinyl benzene cross-linked resin ( PS,chloromethylatedbead ) as starting material,using ethanediamine(EDA ),ethanolamine(ETA ) or ethylene glycol ( EG) as trussarm,the modified PS was prepared by the reaction of truss arm and PS,and then,cyanuric chloride was load-ed to the modified PS by substitution reaction and get polystyrene chlorotriazine resins ’The structure of the pol-ystyrene chlorotriazine resins of the three truss arms were analyzed separately by IR.The results indicated thatthe truss arm with amino was more conducive to modification of PS and conducive to load cyanuric chloride.Considering the quantity of the load of the object,the modified PS by EDA is better than the modified PS byETA and EG,the weight increase ratio of the substitution reaction is 28.1 %,the capacity of loading is 1.48mmol/ g and the chlorine content is 5.9%.The prepared polystyrene chlorotriazine resins can be used as anactive intermediate,which can be made into many functional media by derivatization.
