| 摘 要： | 本文根据过量分子分数的定义，推导出了聚合度关系式：Ｘｎ＝１／（１－Ｐ＋Ｐｑ），它能够用于计算缩聚反应体系的聚合度，控制聚合物的分子量，并以实例阐明了该公式的正确性。该式简便，易于记忆，在缩聚反应中具有普遍意义。

| Abstract: | In this paper, the equation of was obtained in accordance with definition of extra molecular fraction. The equation can be used for calculating degree of polymerization and controlling molecular weight of polymers in polycondensation. The correctness of equation was elucidated by a few examples. It is more simple and easy memory. Therefore, the equation is possessed of the general significace in the polycondensation. |
