    • A process of making a polymeric phenazonium compound having the general formula: wherein R1, R2, R4, R5, R6, R8, and R9 are the same or different, and represent hydrogen, a low alkyl or a substituted aryl, R3 starts with NH2 and is diazotized followed by a polymerization, R5 and R8 may alternatively represent monomeric or polymeric phenazonium radicals, R7 is a carbon in the aromatic ring, Rx and Ry represent any combination of CH3, C2H5, and hydrogen, except that Rx and Ry cannot both be hydrogen, A is an acid radical, and n is an integer from 2 to 100, preferably from 2 to 20 is described. The polymeric phenazonium compound is usable as an additive in a metal plating bath comprising copper. The method includes the steps of a) dissolving an effective amount of an amino compound in a formic acid solution; b) adding a nitrite salt to diazotize the amino compound; and c) adding sulfamic acid to neutralize any excess nitrous acid that may be formed in step b), whereby a polymeric phenazonium compound is produced with a smaller quantity of unreacted monomer remaining in the end product than those produced using methods of the prior art.
    • 制备具有以下通式的聚合物苯扎嗪化合物的方法:其中R1,R2,R4,R5,R6,R8和R9相同或不同,代表氢,低级烷基或取代芳基,R3以NH2 并重氮化后进行聚合,R 5和R 8可以代表单体或聚合苯氮鎓基,R 7是芳环中的碳,R x和R y表示CH 3,C 2 H 5和氢的任何组合,不同之处在于Rx和Ry不能同时 为氢,A为酸基,n为2〜100,优选为2〜20的整数。 聚合物苯扎嗪化合物可用作包含铜的金属电镀浴中的添加剂。 该方法包括以下步骤:a)将有效量的氨基化合物溶解在甲酸溶液中; b)加入亚硝酸盐以重氮化氨基化合物; 和c)加入氨基磺酸以中和步骤b)中可能形成的任何过量的亚硝酸,由此产生与使用现有技术方法制备的那些相比,残留在最终产物中的少量未反应单体的聚合苯扎嗪化合物。
