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