What is claimed is: 1 . An oligomer, comprising: a repeating unit and a repeating unit or a combination thereof, wherein the repeating number of the repeating unit (a) and the repeating number of the repeating unit (b1), (b2), or a combination thereof have a ratio of 1:1 to 20:1; each Q is independently substituted or unsubstituted aliphatic group, cycloaliphatic group, aromatic group, or siloxane group; X is wherein 12≥a≥4; 12≥b≥4; each of R 1 is independently hydrogen, C 4-12 alkyl group, C 4-12 alkenyl group, or C 4-12 alkynyl group, and at least two R 1 is not hydrogen; Y is or a combination thereof, wherein c is 0 or 1; d is 0 or 1; each of R 2′ is independently hydrogen or C 1-10 alkyl group, and at least one of R 2′ is not hydrogen; and each of R 2 is independently hydrogen or C 1-10 alkyl group; and Z is or a combination thereof, wherein 12≥e≥1; 12≥f≥1; 12≥g≥1; and each of R 3 is independently hydrogen or C 1-10 alkyl group. 2 . The oligomer as claimed in claim 1 , wherein the oligomer comprises the repeating units (a), (b1), and (b2), and the repeating number of the repeating unit (b1) and the repeating number of the repeating unit (b2) have a ratio of 1:1 to 5:1. 3 . The oligomer as claimed in claim 1 , wherein the oligomer comprises the repeating units (a) and (b1), and the repeating number of the repeating unit (a) and the repeating number of the repeating unit (b1) have a ratio of 1:1 to 5:1. 4 . The oligomer as claimed in claim 1 , wherein is wherein R 4 is C 1-5 alkylene group, —SO 2 —, —O—, —C(═O)—, or a single bond. 5 . The oligomer as claimed in claim 1 , wherein the repeating unit (a) is and the repeating unit (b1) is 6 . The oligomer as claimed in claim 1 , wherein the repeating unit (a) is and the repeating unit (b1) is 7 . The oligomer as claimed in claim 1 , wherein the repeating unit (a) is and the repeating unit (b1) is 8 . The oligomer as claimed in 1 , wherein the repeating unit (a) is and the repeating unit (b1) is 9 . The oligomer as claimed in 1 , wherein the repeating unit (a) is and the repeating unit (b2) is 10 . The oligomer as claimed in 1 , wherein the repeating unit (a) is the repeating unit (b1) is and the repeating unit (b2) is 11 . The oligomer as claimed in claim 1 , having a terminal amino group or a terminal group modified to contain a double bond. 12 . A composition, comprising: an oligomer; and a radical initiator, wherein the oligomer has a terminal group modified to contain a double bond, and includes: a repeating unit (a) and a repeating unit or a combination thereof, wherein the repeating number of the repeating unit (a) and the repeating number of the repeating unit (b1), (b2) or a combination thereof have a ratio of 1:1 to 20:1; each Q is independently substituted or unsubstituted aliphatic group, cycloaliphatic group, aromatic group, or siloxane group; X is wherein 12≥a≥4; 12≥b≥4; each of R 1 is independently hydrogen, C 4-12 alkyl group, C 4-12 alkenyl group, or C 4-12 alkynyl group, and at least two R 1 is not hydrogen; Y is or a combination thereof, wherein c is 0 or 1; d is 0 or 1; each of R 2′ is independently hydrogen or C 1-10 alkyl group, and at least one of R 2′ is not hydrogen; and each of R 2 is independently hydrogen or C 1-10 alkyl group; and Z is or a combination thereof, wherein 12≥e≥1; 12≥f≥1; 12≥g≥1; and each of R 3 is independently hydrogen or C 1-10 alkyl group. 13 . The composition as claimed in claim 12 , further comprising a polyphenylene ether resin having a terminal methacryloxy group, a polyphenylene ether resin having a terminal vinyl benzyl ether group, or a combination thereof.
