The epoxy/</em><em>PAA/PA</em><em> was evaluated as the effect of </em><em>phthalic anhydride</em><em> composition. The addition of phthalic anhydride increase the elongation at break, energy and impact strength but decreased tensile strength and thermal stability. The optimum of </em><em>energy and </em><em>impact strength was at 20</em><em>wt</em><em>%</em><em> phthalic anhydride</em><em> respectively 0.398 J and 5450</em><em>,48</em><em> J/m<sup>2</sup>.</em> <em>The addition of phthalic anhydride </em><em>decrease the</em><em> thermal properties of epoxy / PAA / PA. Stability of the lowest in the addition of 15</em><em>wt</em><em>% PA around 146<sup>o</sup>C.</em></p&gt;}, number={5s}, journal={International Journal of Advanced Science and Technology}, author={Eduart Wolok, Fahriadi Pakaya}, year={2020}, month={Apr.}, pages={1011 - 1021} }
