- 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.
