Abstract

The KINETICS and mechanism of cure reaction of DGEBA with 4,4’-oxydianiline(ODA) as curing agent in the presence of thermoplastic ABS was studied using isothermal FTIR and dynamic DSC techniques. The activation energy (Ea) by FTIR analysis was evaluated as 36 kJ/mol and decreased to 31 kJ/mol when the amount of ABS was increased from 10% to 30% by weight. Thermodynamic parameters (DH#, DS#, and DG#) for isothermal curing were calculated and the value of DG# did not change significantly by increasing the amount of ABS, while it increased with increasing isothermal curing temperature. The maximum temperature (Tp) of the exothermal peak in DSC thermo gram increased with increasing heating rate. The values of Ea by using DSC data and Kissinger, Ozawa-Flynn-Wall, and is conversional equations were in the range of 55-65 kJ/mol. There was a small decrease in the Ea value by increasing the amount of ABS which can be related to the ease of diffusion of functional groups through the network and/or the catalytic influence of the nitrile group (-CN) on the mechanism of cure reaction.
