摘要: Lactone/alkylene oxide polymers are useful as additives to inhibit or prevent the deposition of paraffin in hydrocarbon fluids, particularly crude oil produced from a subterranean formation. These polymers are random or block polymers 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. In one non-limiting embodiment the lactone monomer is optional.
