Title:
水性系における金属腐食防止ポリマー
Document Type and Number:
Japanese Patent JP4167869
Kind Code:
B2
Abstract:
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.
