The woi’k involves thi’ee Pai’t: Par t one :
Tims part screening the stepwise synthesis of the targeted polymers though
the steps
- The synthesis of 2-mniiio-5-(Substituted phenyl)-1,3,4-tluadiazo1e derivatives (A,-At) via the condensation and cyclizarion of substituted benzoic aid with thiosemicnbazide then the niixtiue was furtliei refluxed by adding warer to give the desM’ed product wluch then neiitrMzed with KOH 10% and wmlied with distil wKer thee tunes and reciystallized from ethanol.
2. The synthesis of l- Bg) derives though a substitution reaction of derivatives
(A,-At) with a11y1 chloride in the pieserve of few di’op of tnetliyl anuiie and using dimetliylfoniiaide DkIF as a solvent the product wmlied with water tluee tiiiies and reciystallized from ethanol.
- This step involves the synthesis of the cross-linked polyineiization technique and free i’adicN polymerization iiiethod by mixing appropriate mnoimts of derivatives (B l- B t), aciylic acid, iiietliyleiiebisacrylomide (MBA) iii benzene and then a few amoimt of azobisisobutyi’onitrile (AIB N) the well know iiutiator we added nd the inixtiue was reduxed for 6 moms, aftei cooling the precipitated was washed with iiietlimiol to iemove any iuueacted species.
Par t two:
Tlus parts involves the characterization of the synthesized polymei using
FT-IR, TGA and SEM.
Par t three:
Tlus parts wolves the applications studied such as the solubility that was tested ining strong acidic medium (HC1 10%) nd strong basic medium (NaOH 10%) nd some mostly used oigmuc solvent like dimethyl formmnide (DMF), tetra hydro fui’mi (THF), Dunethyl Sulfoxide (DM SO), acetone, ethyl acetKe, diethyl ether, metlimiol and ethmiol.
The swelling was studied for the synthesized polymers using two solvents iiiethwol nd water and calculKed amounts of each polymer wlucli was incubated foi 24 hour’s,
The adsorption of metal ions such as Ni(II),Co(II) and Fe(III) ions was studied to investigate the ability ,of the polymers foi reiiioving of these ions from their ionic solutions and the results were reasonable especially with Fe
