Claims
- 1. A process for breaking a water-in-oil emulsion which comprises contacting said emulsion with a substrate which is coated with an alkylphenol-polyethylene oxide-acrylate polymer.
- 2. The process of claim 1 in which the oil of said emulsion is a naturally occurring crude petroleum oil.
- 3. The process of claim 2 in which the alkyl group of the alkylphenol component of the polymer contains from 4 to 16 carbon atoms and the polyethylene oxide chains in the polymer contain from 6 to 12 units.
- 4. The process of claim 3 in which the acrylate is an alkylacrylate in which the alkyl group contains up to 4 carbon atoms.
- 5. The process of claim 4 in which a second monomer selected from the group consisting of (a) unsubstituted aryl acrylates containing one or more aromatic rings, (b) alkyl substituted aryl acrylates containing one or more aromatic rings and in which the alkyl group contains up to 8 carbon atoms, (c) unsubstituted acrylate, and (d) alkyl substituted acrylates in which the alkyl group contains up to 4 carbon atoms.
