摘要
用FT-IR研究了液晶环氧-4,4′-二缩水甘油醚基二苯基酰氧(PHBHQ)与4,4′-二氨基二苯甲烷(DDM)固化反应的动力学,研究表明,PHBHQ与DDM的固化反应按自催化反应机理进行,固化过程=66.51kJ/mol,lnA1=中产生的羟基可进一步加速反应,计算出分步反应的动力学参数分别为Ea1=69.05kJ/mol,lnA2=7.34。6.65。
The curing mechanism and kinetics of liquid crystalline epoxy resin--4-epoxypropoxy phenyl-4′-epoxypropxy benzoate (PHBHQ) with DDM were studied by using Flourier Transmit Infrared (FT-IR). The curing reaction proceeded in auto-accelerate reacting mechanism and is accelerated by the hydroxyl group produced in the system. The kinetics parameters of each step of curing reaction were calculated: E_(a1)=(66.51) kJ/mol, ln A_1=(6.65), E_(a2)=( 69.05) kJ/mol, ln A_2=(7.34).
