In this paper, polyisobutylene succinic anhydride adduct (PIB‐SA) was modified by esterification with polyethylene glycol (PEG 600, 1000 and 2000) to obtain mono‐ and diterminal polyoxyalkynated PIB‐SA. The monoterminal products were reacted with pentamethylene‐hexamine (PMHA). The structures were confirmed by FT–IR and 1H NMR analysis. The surface properties, interfacial tension and the effectiveness in oil dispersion of the synthesized polymeric surfactants are reported. The maximum efficiency of oil spill dispersants was reached when the surfactant molecule had two moities (polyoxyalkylene and polyamine units). © 1999 Society of Chemical Industry
