The sulfide group-containing polyester is obtained by subjecting a reaction composition to esterification and condensation reactions. The reaction composition includes an aromatic diacid component and a diol component including aliphatic diol and a diol compound represented by the following formula (I): HO—(X1—O)n—X3—S—X4—(O—X2)m—OH (I) wherein X1 and X2 independently represent a C1-C6 alkylene group, X3 and X4 represent a C6-C10 arylene group, and m and n represent an integer ranging from 1 to 5. The catalyst is for inducing reaction between the sulfide group-containing polyester and oxygen. ## Claims ### Claim 1 An oxygen-scavenging composition comprising: a sulfide group-containing polyester obtained by subjecting a reaction composition to esterification and condensation reactions, said reaction composition including an aromatic diacid component and a diol component that includes aliphatic diol and a diol compound; and a catalyst for inducing reaction between said sulfide group-containing polyester and oxygen; wherein said diol compound is represented by the following formula (I): HO—(X1—O)n—X3—S—X4—(O—X2)m—OH (I) wherein X1 and X2 independently represent a C1-C6 alkylene group, X3 and X4 independently represent a C6-C10 arylene group, and m and n independently represent an integer ranging from 1 to 5. ### Claim 2 (depends on 1) The oxygen-scavenging composition as claimed in claim 1, wherein X1 and X2 independently represent an ethylene group, X3 and X4 independently represent a phenylene group, and m and n independently represent 1. ### Claim 3 (depends on 1) The oxygen-scavenging composition as claimed in claim 1, wherein said diol compound is in an amount ranging from 1 mol % to 70 mol % based on the total moles of said diol component. ### Claim 4 (depends on 3) The oxygen-scavenging composition as claimed in claim 3, wherein said diol compound is in an amount ranging from 5 to 50 mol %. ### Claim 5 (depends on 1) The oxygen-scavenging composition as claimed in claim 1, wherein said aromatic diacid component of said reaction composition includes C8-C14 aromatic dicarboxylic acid. ### Claim 6 (depends on 1) The oxygen-scavenging composition as claimed in claim 1, wherein said aliphatic diol of said diol component of said reaction composition includes C2-C12 aliphatic diol. ### Claim 7 (depends on 1) The oxygen-scavenging composition as claimed in claim 1, wherein said catalyst includes a transition metal-containing catalyst. ### Claim 8 (depends on 7) The oxygen-scavenging composition as claimed in claim 7, wherein said transition metal-containing catalyst is selected from the group consisting of cobalt neodecanoate, cobalt acetate, ferric chloride, cobalt chloride, nickel sulfate, cobalt sulfate, manganese sulfate, molybdenyl acetylacetonate, molybdenum carbide, hexacarbonyl molybdenum, molybdenum trioxide, and combinations thereof. ### Claim 9 (depends on 1) The oxygen-scavenging composition as claimed in claim 1, wherein said catalyst is in an amount ranging from 0.01 to 0.15 part by weight based on 100 parts by weight of the oxygen-scavenging composition. ### Claim 10 A sulfide group-containing polyester, obtained by subjecting a reaction composition to condensation and esterification reactions, said reaction composition including an aromatic diacid component and a diol component that includes aliphatic diol and a diol compound, said diol compound being represented by the following formula (I): HO—(X1—O)n—X3—S—X4—(O—X2)m—OH (I) wherein X1 and X2 independently represent a C1-C6 alkylene group, X3 and X4 independently represent a C6-C10 arylene group, and m and n independently represent an integer ranging from 1 to 5. ### Claim 11 (depends on 10) The sulfide group-containing polyester as claimed in claim 10, wherein X1 and X2 independently represent an ethylene group, X3 and X4 independently represent a phenylene group, and m and n independently represent 1. ### Claim 12 (depends on 10) The sulfide group-containing polyester as claimed in claim 10, wherein said diol compound is in an amount ranging from 1 mol % to 70 mol % based on the total moles of said reaction composition. ### Claim 13 (depends on 12) The sulfide group-containing polyester as claimed in claim 12, wherein said diol compound is in an amount ranging from 5 to 50 mol %. ### Claim 14 (depends on 10) The sulfide group-containing polyester as claimed in claim 10, wherein said aromatic diacid component of said reaction composition includes a C8-C14 aromatic dicarboxylic acid. ### Claim 15 (depends on 10) The sulfide group-containing polyester as claimed in claim 10, wherein said aliphatic diol of said diol component of said reaction composition includes a C2-C12 aliphatic diol. ### Claim 16 (depends on 1) An oxygen-scavenging packaging article, comprising the oxygen-scavenging composition as claimed in claim 1.
