CORROSION INHIBITING COMPOSITIONS

摘要

A new class of polymeric corrosion inhibiting compositions incorporating pendant heterocyclic groups which are surprisingly effective copper corrosion inhibitors are disclosed. The polymers form a protective barrier on metallic components to aqueous systems and remain substantive on metallic surfaces over a wide pH range. Moreover, the polymers are resistant to oxidizing biocides, and are substantially impervious to repeated or prolonged exposure to corrosive agents.
