Abstract
Various 2-(4-ethyl-1-piperazinylo)-4,6-bisarylhydrazino-1,3,5-triazine (3a–f) were prepared by the reaction of 2-(4-ethyl-1-piperazinylo)-4,6-dichloro-1,3,5-triazine and various phenyl hydrazine derivatives. All the 3a–f derivatives were characterized by elemental analysis and IR spectral studies. All the 3a–f compounds were screened for microbial activity against gram-positive and gram-negative bacteria. All these derivatives were employed as the epoxy resin curing agent. Thus the curing of the epoxy diglycidyl ether of bisphenol-A (DGEBA) was monitored by differential scanning calorimeter (DSC). Based on DSC parameters and glass-fiber reinforced composites based on DGEBA-3(a-f) systems were prepared and characterized.
