| Abstract: | Summary The objective of this study was to investigate the effects of the amine terminated poly(arylene ether ketone) (PAEK) oligomers
as epoxy tougheners on the mechanical and thermal properties of diglycidyl ether of bisphenol A based epoxy resin. The reactive
oligomers including pendant tertiary butyl groups were synthesized by nucleophilic aromatic substitution reaction and molecular
weight of the oligomers were controlled through end group functionalization and characterized by FTIR spectroscopy. The stoichiometrical
amount of the reactive oligomers as toughener and the curing agent, 4,4’-diaminodiphenyl sulfone (DDS) were mixed and degassed.
The homogenous mixtures were cured at 120 °C into the preheated molds. The mechanical and thermal characterizations of toughened
epoxy resin system were evaluated. It has been shown that the mechanical and thermal properties of toughened epoxy system
vary as a function of the chemical structure and the concentration of reactive oligomers.
