POLYMERS HAVING TERMINAL AMINO GROUPS AND USE THEREOF AS ADDITIVES FOR ZINC AND ZINC ALLOY ELECTRODEPOSITION BATHS |
摘要 |
<p>Additives for electrolyte baths for the electrodeposition of zinc or zinc alloy layer are described. The additives are polymers with terminal amino groups. These polymers are obtainable by reaction of at least one diamino compound (having two tertiary amino groups) with at least one di(pseudo)halogen compound, wherein the diamino compound is used in stoichiometric excess. The additives effect, in particular, a very little formation of bubbles and only few burnings as well as a uniform distribution of layer thickness in the electrodeposition of zinc or zinc alloy layers.</p> |
