The four reaction channels including hydroxyl-type benzaldoxime are endothermic reaction, thermodynamically non-spontaneous process, but the other four reaction channels including ion-type benzaldoxime participation are exothermic reaction and thermodynamically spontaneous process. The latter four reaction channels, which have lower reaction barriers, faster reaction velocities and bigger equilibrium constants than those of the former fours, are the chief reaction channels.

苯甲醛肟以羟基型参与反应的4个反应通道均为吸热反应和热力学非自发过程，它们均具有较高的反应势垒、较慢的反应速率和较小的平衡常数；而以离子型参与反应的四个反应通道均为放热反应和热力学自发过程，它们的反应势垒较低，反应速度较快，平衡常数也较大，故苯甲醛肟应主要以离子型参与反应。

The optimum reaction conditions are obtained by orthogonal exptl. design; ring-opening reaction:n:n = 1:1.3, Hexamethylenetetramine catalyst 0.7%,reaction temp. is 80℃, reaction time is 7 h, and concentration of inhibitor is 0.3%. ring-closing reaction : n:n=1:0.9, reaction temp. is 40℃, reaction time is 5 h.

通过正交设计确定了最佳工艺条件为：开环反应：六次甲基四胺用量0.7%(占反应物总量的质量百分比)，阻聚剂用量0.3%(占反应物总量的质量百分比)，ECH：MAA的摩尔比为1.3：1，温度80℃，反应时间7h ；闭环反应：氯醇酯： NaOH的摩尔比为1：0.9，反应温度40℃，反应时间5h。

The results demonstrated that the fractional conversion and reaction rate were rapidly increased in the initial curing reaction. The higher the curing temperature, the higher the fractional conversion and reaction rate was. With increasing of the curing temperature and time, the fractional conversion and reaction rate decreased and became constantly. The initial curing reaction was a first order reaction. The apparent activation energy and frequency factor of curing reaction used G- capryl ester was bigger than that of used G-oligomer.

结果表明：固化体系在研究的固化温度下，转化率和反应速率在固化反应初期增加快速，温度越高增加越快，随着固化时间的延长，这种变化逐渐变慢，并最终趋于恒定；初期固化反应为一级反应，反应初期的表观活化能和指前因子大小顺序为G-预聚体＞G-辛酯。
