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.
本发明公开了一类新型聚合物缓蚀组合物,其中包含的悬垂杂环基团是令人惊讶的有效
铜缓蚀剂。这种聚合物可在
金属部件与
水性体系之间形成保护屏障,并在较宽的 pH 值范围内保持
金属表面的实质性。此外,这种聚合物还能抵抗氧化性杀菌剂,而且基本上不会反复或长期暴露于腐蚀性介质中。
