Abstract
2-(4-ethyl-1-piperazinylo)-4,6-bismaleatedethylamino-1,3,5-triazine (EBT) was prepared by the reaction of 2-(4-ethyl-1-piperazinylo)-4,6-bishydroxyethylamino-1,3,5-triazine and maleic anhydride. The EBT derivative was characterized by elemental analysis, acid value and spectral studies. EBT was then polycondensed respectively with three commercial epoxy resins, namely diglycidyl ether of bisphenol-A (DGEBA), diglycidyl ether of bisphenol-F (DGEBF) and diglycidyl ether of bisphenol-C (DGEBC). The resultant polymers are designated as unsaturated polyester-s-triazine (UPETs) and were characterized by elemental analysis, spectral study, molecular weight determination, differential scanning calorimeter (DSC)and thermogravimetry. The interacting blends of UPETs with DGEBA epoxy resin was made at stoichiometric ratio. The blending of these systems was monitored on a differential scanning calorimeter (DSC), and based on DSC data the glass-reinforced composites (GRCs) were prepared and characterized by physical and mechanical properties.
