Title: (EN) Novel Copolymers for Use as Oilfield Demulsifiers
Abstract:
(EN)

Lactone/alkylene oxide polymers are useful as demulsifiers to break emulsions, e.g. water-in-oil and oil-in-water emulsions, particularly oilfield emulsions. These polymers are random or block polymer made from addition reactions of a hydroxyl- and/or amine-containing base compound with at least one lactone monomer and at least one alkylene oxide monomer.
