An article comprising: a packaging container, or a portion thereof, having: a metal substrate; a coating composition that is substantially free of bisphenol A or the diglycidyl ether of bisphenol A applied on at least a portion of the metal substrate, the coating composition comprising: a polyether polymer that includes one or more segments of the below Formula: wherein: each of the oxygen atoms depicted in Formula is present in an ether linkage; each R 1 is independently an atom or group having an atomic weight of at least 15 daltons; v is independently 1 to 4; w is 4; each of the phenylene groups depicted in Formula includes at least one R 1 attached to the ring at an ortho position relative to the depicted oxygen atom; R 2, if present, is a divalent group; n is 0 or 1; with the proviso that if n is 0, the phenylene groups depicted in Formula can optionally join to form a fused ring system in which case w is 3; and two or more R 1 and/or R 2 groups can join to form one or more cyclic groups. a packaging container, or a portion thereof, having: a metal substrate; a coating composition that is substantially free of bisphenol A or the diglycidyl ether of bisphenol A applied on at least a portion of the metal substrate, the coating composition comprising: a polyether polymer that includes one or more segments of the below Formula: wherein: each of the oxygen atoms depicted in Formula is present in an ether linkage; each R 1 is independently an atom or group having an atomic weight of at least 15 daltons; v is independently 1 to 4; w is 4; each of the phenylene groups depicted in Formula includes at least one R 1 attached to the ring at an ortho position relative to the depicted oxygen atom; R 2, if present, is a divalent group; n is 0 or 1; with the proviso that if n is 0, the phenylene groups depicted in Formula can optionally join to form a fused ring system in which case w is 3; and two or more R 1 and/or R 2 groups can join to form one or more cyclic groups. a metal substrate; a coating composition that is substantially free of bisphenol A or the diglycidyl ether of bisphenol A applied on at least a portion of the metal substrate, the coating composition comprising: a polyether polymer that includes one or more segments of the below Formula: wherein: each of the oxygen atoms depicted in Formula is present in an ether linkage; each R 1 is independently an atom or group having an atomic weight of at least 15 daltons; v is independently 1 to 4; w is 4; each of the phenylene groups depicted in Formula includes at least one R 1 attached to the ring at an ortho position relative to the depicted oxygen atom; R 2, if present, is a divalent group; n is 0 or 1; with the proviso that if n is 0, the phenylene groups depicted in Formula can optionally join to form a fused ring system in which case w is 3; and two or more R 1 and/or R 2 groups can join to form one or more cyclic groups. a polyether polymer that includes one or more segments of the below Formula: wherein: each of the oxygen atoms depicted in Formula is present in an ether linkage; each R 1 is independently an atom or group having an atomic weight of at least 15 daltons; v is independently 1 to 4; w is 4; each of the phenylene groups depicted in Formula includes at least one R 1 attached to the ring at an ortho position relative to the depicted oxygen atom; R 2, if present, is a divalent group; n is 0 or 1; with the proviso that if n is 0, the phenylene groups depicted in Formula can optionally join to form a fused ring system in which case w is 3; and two or more R 1 and/or R 2 groups can join to form one or more cyclic groups. each of the oxygen atoms depicted in Formula is present in an ether linkage; each R 1 is independently an atom or group having an atomic weight of at least 15 daltons; v is independently 1 to 4; w is 4; each of the phenylene groups depicted in Formula includes at least one R 1 attached to the ring at an ortho position relative to the depicted oxygen atom; R 2, if present, is a divalent group; n is 0 or 1; with the proviso that if n is 0, the phenylene groups depicted in Formula can optionally join to form a fused ring system in which case w is 3; and two or more R 1 and/or R 2 groups can join to form one or more cyclic groups.
