以PP-St-DVB接枝纤维为起始原料,氯乙酰氯为酰基化试剂、三氯化铝为催化剂,采用傅-克酰基化反应的方法,避免了强碱纤维制备过程中使用致癌性的氯甲醚,优化了溶胀时间、反应温度、反应时间、氯乙酰氯用量、催化剂用量对酰基化后纤维增重率的影响,接枝率大于等于135％的PP-St-DVB纤维最终季铵化反应后可以得到3.0 mmol/g以上的新型强碱离子交换纤维.“,”Fuctional chloracetylated fiber carriers was prepared via the Friedel-Crafts acetylation of PP-St-DVB fiber by using chloroacetyl chloride as the acylation reagent and taking aluminum trichloride as the catalyst,and to avoided to use carcinogenic compound of chloromethyl ether.The effects of the swelling time,reaction temperature,reaction time,the amount of chloroacetyl chloride and catalyst on weight gain rate after the fiber chloroacetylation were optimized.And finally a new srong base anion exchange fiber was synthesized when the obtained ion exchange fiber exhibited the exchange capacity as high as 3.0 mmol/g and the graft yield of PP-St-DVB fiber was greater than or equal to 135％.
