Novel Piperazinylo Bisaryl Hydrazino-S-Triazine Derivatives and Their Application as Epoxy Resin Curing Agents

摘要

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.View full textDownload full textKeywordsantimicrobial activity, composites, DSC, epoxy resin, hydrazines, IR and spectral study, piperazinylobisarylhydrazino-s-triazine derivativesRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00914030902852336
