摘　　要：以聚丙烯接枝苯乙烯纤维为原料,采用乙酰化及胺基化两步法反应,制备多胺基离子交换纤维。研究了反应时间和温度、催化剂及乙酰氯用量对乙酰化反应条件的影响。利用正交实验法研究了胺酰摩尔比、胺醛摩尔比、胺酸摩尔比及反应时间对胺化反应影响。所制备的胺基纤维对Cu2+吸附容量可达2.00mmol/g。A kind of novel amino fiber was prepared from styrene grafted polypropylene （PP-g-St） fiber through acetylation and amination reaction. Factors affecting the acetylation process, such as reaction time, temperature, catalyst and the amount of acetyl chloride, were investigated. The effects of mol-ratio of amine vs. acetyl, amine vs. paraformaldehyde and amine vs. hydrochloric plus reaction time were also studied to obtain the opti- mum amination conditions by orthogonal experiment design. The results show that the adsorption capacity of Cu^2＋ could reach 2.00mmol/g by this kind of amino fiber.
