An oxygen-scavenging composition includes a sulfide group-containing polyester and a catalyst. 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.
An oxygen-scavenging composition comprising:
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):
