摘要：
Amino sulfonic acid based polymers are reaction products of amino sulfonic acids, an amine, polyepoxide compounds and epihalohydrin. The polymers may be used as levelers in copper electroplating baths, to provide good throwing power. Such reaction products may plate copper or copper alloys with good surface properties and good physical reliability.
