摘要
利用傅里叶变换红外光谱仪(FTIR)在线追踪聚乙烯基苄基氯(PVBCl)与N,N,N′,N′-四甲基-1,6-己二胺(TMHDA)的交联反应历程,考察了反应时间与温度对交联程度的影响。实验结果表明,随着反应时间的延长,交联程度先迅速增大,而后趋于平缓直至不变;反应温度越高,交联程度越大。对反应进行动力学的研究计算结果显示,该交联反应的反应级数n=4,表观活化能Ea=97.2kJ/mol。
By use of real-time FTIR to track the crosslinking reaction course between poly（vinylbenzyl chloride） （PVBCI） and N, N, N＇ , N＇-tetramethybl, 6-diaminohexane（TMHDA）, the effects of reactioa time and temperature on the degree of crosslinking were studied. The experimental results demonstrated that the degree of crosslinking increased rapidly at first, and then gone slowly to a constant value with the increase of reaction time. It was also shown that the degree of crosslinking was increased with the increasing of reaction temperature. In addition the kinetics parameters of the reaction were calculated. The results showed that the reaction order （n） was 4 and the reaction activation energy （Ea,） was about 97.2kJ/mol.
