Properties of coolygomer based on 4-ızopropenylphenol and maleıc anhydrıde, theır structurıng product with ethylenedıamıne and formaldehyde

By the reaction of olygomer based on 4-izopropenylphenol and maleic anhydride with ethylenediamine and formaldehyde (on Mannic reaction) crosslinked polymer was obtained.Olygomer based on 4-izopropenylphenol and maleic anhydride was obtained by radical olygomerization of 4izopropenylphenol with maleic anhydride in the presence of initiator.Condensation reaction of the obtained olygomer with formaldehyde and ethylenediamine was carried out for 3 h at 80-85 C.Their structures were determined by IR spectra and elemental analysis.Their thermal analysis was studied and high thermal stability was revealed.Sorption property in water systems of cross-linked polymer was revealed for extracting of uranyl ions.It was determined that cross-linked polymer have 89-91% sorption degree which is achieved at pH 7-9.In this case, the sorption capacity (SC) of the crosslinked polymer is ~230-235 mg/g.Cross-linked polymer also was studied as sorbent for extracting of microelements from oil formation waters associated with Azerbaijan oils from the Lokbatan fields of the Karadag region and Bibiheybat of the Sabail region.It was revealed that synthesised sorbent can be applied for extracting of microelements from oil formation waters.Thus, 100% sorption is achieved in formation water A for Na, Zn, Cu, Cr, Mn and Se.For K, Ca, Ba, Hg, Fe and As, the degree of sorption of sorbents 67 is 98.6, 99.7, 97.2, 99.3, 93.7, 99.9%, respectively
