A demulsifier comprising: a vinyl polymer having a site capable of being alkoxylated; and at least one alkylene oxide selected from the group consisting of: ethylene oxide, propylene oxide, butylene oxide, and the like. For example, ethylene oxide may be present in an amount of about 1 to 40 weight percent, and/or propylene oxide may be present in an amount of about 1 to 40 weight percent. The vinyl polymer contains at least one hydrophobic monomer and at least one hydrophilic monomer, wherein the hydrophobic monomer and/or the hydrophilic monomer contain sites which are capable of being alkoxylated.
