摘　　要：由卤代次甲基化合物标样分别与对甲苯硫代磺酸钾(化合物1)、对甲苯亚磺酸钠(化合物2)及对甲苯磺酰肼基二硫代甲酸钾(化合物3)进行反应,发现化合物3与标样反应最快.因此,通过三步反应将该基团接枝到聚苯乙烯白球上:树脂白球氯磺化得到聚苯乙烯基磺酰氯树脂(树脂4),树脂4与水合肼反应制备聚苯乙烯基磺酰肼树脂(树脂5),树脂5在碱性条件下与二硫化碳反应得到了聚苯乙烯磺酰肼基二硫代甲酸盐树脂(树脂6).并研究了静态条件下树脂6去除卤代次甲基化合物的能力.By comparing the reactions of the halomethylene standards with potassium thioto-sylate (1), sodium toluenesulfinate (2) and potassium salt of tosylhydrazinecarbodithioic acid (3) respectively, it is found that compound 3 is the most active. This group was grafted on polystyrene beads through three steps : chlorosulfonation to get polystyryl-sulfonyl chloride (4), then resin 4 reacted with hydrazine to obtain polystyryl-sulfonylhydrazine (5), which was treated with carbon disulfide in presence of base to prepare the resin of salt of polystyrylsulfonylhydrazinecarbodithioic acid (6). The initial results of it's ability of removing halomethylene compounds in static state is reported.
