| Abstract: | Near infrared spectroscopy is to study the reactions between phenyl glycidyl ether and three aromatic amines simultaneously respectively. In order to study the mechanism of curing reaction were analysed by computer. It was indicated that the curing reaction proceeds in auto-accelerated reacting mechanism and is accelerated by the hydeoxyl groups produced in the system. Theactivation energies of curing reactions were calculated: E_(a1)= 45.96kJ. mol~(-1) ,B_(a2)= 64.50kJ. mol~(-1). |
