摘　　要：讨论了准确测定马来酸酐接枝聚丙烯(PP-g-MAH)接枝率的意义,介绍了两种常见测定接枝率的方法。系统分析酸碱滴定法测定PP-g-MAH接枝率的实验操作过程,研究结合红外分光光度法,拟合线性工作曲线,得到快速测定产品实际接枝率的实验方法。The importance of accurately determining the grafting ratio of maleic anhydride grafted polypropylene(PP-g-MAH)was discussed,and two general methods for determining the grafting ratio were summarized.A facile,accurate and rapid method to determine the grafting ratio of the PP-g-MAH was developed.The actual grafting ratio was determined by acid-base titration combining with infrared spectrophotometry and fitting the linear working curve.
