Abstract
A composition comprising one or more siloxane cross-linked demulsifiers wherein said siloxane cross-linked demulsifiers are prepared by reacting one or more alkylphenol-formaldehyde resin alkoxylates, one or more polyalkylene glycols, or a mixture thereof, with up to about 1.0 molar equivalents of one or more cross-linkers of formula R1R2R3R4Si wherein R1, R2, R3 and R4 are independently selected from H, Cl, C1-C4 alkyl and C1-C4 alkoxy and a method of using the demulsifier composition to resolve water-in-oil emulsions.
