A composition useful as a biodegradable corrosion inhibitor and a biocide that comprises a polymeric quaternary ammonium salt prepared by a reaction of a pplyepihalohydrin with a tertiary amine, wherein the polyepihalohydrin is prepared by a polymerization reaction of an epihalohydrin in the presence of a monomeric poly alcohol and delivered to the corrosion system in a solvent carrier.
L'invention concerne une composition utilisée comme inhibiteur de corrosion biodégradable, et un biocide contenant un sel d'ammonium quaternaire polymérique préparé par réaction d'une polyépihalohydrine avec une amine tertiaire. La polyépihalohydrine est obtenue à partir d'une réaction de polymérisation d'une épihalohydrine en présence d'un polyalcool monomérique, et distribuée au système de corrosion dans un support de solvant.
