Synthesis of poly(caprolactone)-block-poly[oligo(ethylene glycol)methyl methacrylate] amphiphilic grafted nanoparticles (AGNs) as improved oil dispersants

Amphiphilic polymers have been covalently grafted from a SiO 2 core with room temperature polymerizations. These amphiphilic grafted nanoparticles have been found to uptake up to 30 times their mass in crude oil within a 24 hour window.
