    摘要： Herein are disclosed polymeric metal salts useful in catalyzing oxygen scavenging by oxygen scavenging polymers. The polymeric metal salts comprise structure I: wherein R is selected from C1--C20 alkyl, C5-C20 cycloalkyl, C2-C40 branched alkyl, C2-C40 branched alkyl acid or diacid, C2-C12 alkenyl, C5-C12 cycloalkenyl, C2-C40 branched alkenyl, or C2-C40 branched alkenyl acid or diacid; and M is selected from manganese, iron, cobalt, nickel, copper, rhodium, or ruthenium. These polymeric metal salts are substantially non-extractable from a packaging article comprising the metal salts. Also disclosed are packaging articles comprising the polymeric metal salts, and methods of synthesizing the polymeric metal salts.
