| 无机阻燃材料聚磷酸铵聚合度测定的新方法 |

| 摘 要： | 用端基滴定法测聚磷酸盐的分子数，用差示分光光度法测聚磷酸盐的总含磷量，建立了一种端基单次滴定－光度法测定聚磷酸盐的聚合度的新方法。在单次滴定法中利用导数曲线使化学计量点更加明确，可使测定聚磷酸盐分子数的误差大为减小。该方法不需长达５ｈ的回流等繁锁过程。此方法省时，操作简单，准确度高。

| Abstract: | With single end socket detrition method,the moles of polyphosphate salts were measured.The total amount of phospharus of the salts were determined by differential spectrosmetry.A new method of measurement of the degree of polymerization for that salts was obtained.The method can save time,and is simple and accurate. |
