Abstract
A chemorheological study of biphenyl-type epoxy/phenol novolac system was performed at different isothermal curing temperatures. To predict the chemoviscosity during isothermal curing reaction, modified Williams-Landel-Ferry (WLF) equation was used. Glass transition temperature change due to curing reaction measured, by DSC could be expressed as a function of conversion. From the measurements of isothermal viscosity, C 1 and C 2 in WLF equation were found to have an Arrhenius-type dependence on temperature. By using these relations in conjunction with modified WLF equation, good agreement between predicted and experimental viscosity was observed.
