چکیده مقاله
Epoxy–amine networks based on diglycidyl ether of biphenyl A (DGEBA) and aliphatic/aromatic diamines are widely used in different industrial applications such as coatings, adhesives and composite materials, due to their outstanding chemical and mechanical properties, [1-2]. Recently, we compared thermal and mechanical properties of epoxy networks cured with α,ω-diamino polyoxytetramethylene (APOTM) and isophorone diamine. According to the tan δ-T plots, epoxy network cured with APOTM shows Tg value lower than epoxy network cured with IPD (Fig. 1). Wide range of properties may be developed via the embodiment of APOTM into epoxy resin formulations. Low shrinkage, good color, flexibility and tough, high gloss are characteristics of epoxy resins cured with APOTM. Improvement of the segment flexibility reduces the Tg of the epoxy network.
