    • The invention relates to a polymeric corrosion inhibiter for a metal substrate of formula (R1)aA(R2X)b, where a=0-3, b=1-6, A is a bridge structure unit, R1 is identical to or different from H or an aliphatic, aromatic, olefinic, cyclic, heterocyclic, polycyclic or polyheterocyclic radical, R2 is identical to or different from a polymeric basic structure, X is identical to or different from a functional group selected from the groups comprising: carboxylic acids; dicarboxylic acids; polycarboxylic acids; carboxylic acid anhydrides; carboxylic acid chlorides; carboxylic sulfonic acids; and also esters, amides and imides of the aforementioned groups, the molar mass of the polymer lies between 200 and 10,000, preferably 400 and 6,000. The invention further relates to the use of a polymeric corrosion inhibiter for the treatment of metal surfaces and to a method for producing a polymeric corrosion inhibiter.
    • 本发明涉及一种用于式(R1)aA(R2X)b的金属基质的聚合物腐蚀抑制剂,其中a = 0-3,b = 1-6,A是桥结构单元,R 1相同或不同 H或脂族,芳族,烯属,环状,杂环,多环或多杂环基,R 2与聚合碱性结构相同或不同,X与选自以下的官能团相同或不同:羧酸; 二羧酸; 多元羧酸 羧酸酐 羧酸氯化物; 羧酸磺酸; 以及上述基团的酯,酰胺和酰亚胺,聚合物的摩尔质量在200和10,000之间,优选400和6,000。 本发明还涉及聚合物腐蚀抑制剂在金属表面处理中的应用以及生产聚合物腐蚀抑制剂的方法。
