An analytical comparative study was performed between the prepared emulsifiers polyisobutylene succinic anhydride (PIBSA) and the commercial LZ2735 and LZ2745 materials. The PIBSA-1, -2 and PIBSA/TEA were prepared by reacting the reactive polyisobutene (PIB) with maleic anhydride via isothermal heating at 250°C for 10 h. Then, PIBSA was heated with triethanolamine at 80°C for 2 h to give PIBSA/TEA. The structures of the prepared PIBSA-1, PIBSA-2, PIBSA/TEA, PIBSA/TEA-1, PIBSA/TEA-2, LZ2735 and LZ2745 were characterized by FTIR, 1H-, 13C-NMR spectroscopy and Gel permeation chromatography (GPC). The FTIR spectra of PIBSA-1 and -2 showed absorption carbonyl bands at 1711 and 1783 cm-1 due to carbonyl anhydride stretching vibrations of the succinic anhydride (SA), whereas a relevant band appeared at 1732 cm-1 for LZ2735 and LZ2745. PIBSA/TEA was identified by a hump of amine group around 3351 cm-1. 13C-NMR of the PIBSA-1 and -2 indicated signals at δ 57.6 and 59.5 ppm. The GPC showed polydispersity index which used as a measure of the broadness of a molecular weight distribution of our samples together with the presence of a significant amount of number average molecular weight (Mn). The amber colored products were viscous and the prepared emulsions were used for blending the emulsion explosives, detergents, cosmetics, paintings to remove lead from polluted waste water.
