✦ Synopsis

In this paper, polyisobutylene succinic anhydride adduct (PIB-SA) was modi®ed by esteri-®cation 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 con®rmed by FT±IR and 1 H NMR analysis. The surface properties, interfacial tension and the effectiveness in oil dispersion of the synthesized polymeric surfactants are reported. The maximum ef®ciency of oil spill dispersants was reached when the surfactant molecule had two moities (polyoxyalkylene and polyamine units).

## Abstract **Summary:** Poly(propylene) (PP)‐clay nanocomposites were prepared from unmodified montmorillonite clays (NaMMT), with poly(ethylene oxide)‐based nonionic surfactants as dispersants/intercalants/exfoliants. The primary objective of this research was to find dispersants that (a) allow P
