<p>The present invention provides methods for recovering fossil-based materials from oil sources using multifunctional, multipolymer surfactants. The invention also provides methods for reducing the loss of volatile organic compounds (VOCs) from oil storage containers using multifunctional, multipolymer surfactants. The multifunctional, multipolymer surfactants are characterized by a hydrophobic part and a hydrophilic part. The hydrophobic part of the polymer surfactants includes functionalities that impart a polarity of greater than 0 Debye to the hydrophobic part. The polymer surfactants are further characterized by molecular weights that are above their entanglement weights. The result is polymer surfactants with demulsifying characteristics.</p> |
