| 摘 要： | 本文建立了两个相关的∑Aa_i-B_2型凝胶化反应方程,含试样官能团数和重均官能度两个未知数.解联立方程,得到一元二次方程.通过测定该方程的系数,间接测得试样官能团数和重均官能度.该方法用于H_2O_2引发的羟基聚丁二烯羟值测定。其结果比目前国内外通用的经典酰化法高一倍以上.证明新的羟值数据是正确的.

| Abstract: | The present paper establishes two equations on gelation reaction of type ∑Aa1-B2, containing two unknown numbers of functional group and weight average functionality. A quadratic equation is obtained by solving the simultaneous equation. Coefficient of the equation, functional group number and weight average functionality indirectly measured. When the method is applied to hydroxyl number determination of HTPB initiated by H2O3, the hydroxyl number is two times as large as one obtained by existing classical acetylizing method. |
