Abstract: An oligomer includes a repeating unit




and a repeating unit




or a combination thereof. 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 can be




and Y can be




or a combination thereof, and Z can be




or a combination thereof.

Abstract: A polycarbonate diol is provided. The polycarbonate diol includes repeating units represented by formula (A) and formula (B), and hydroxyl groups located at both ends of the polycarbonate diol. The molar ratio of formula (A) to formula (B) is in a range from 1:99 to 99:1. R1 is a linear, branched or cyclic C2-20 alkylene group. R2 is a linear or branched C2-10 alkylene group; m and n are independently and can be an integer from 0 to 10, and m+n≥1. A is a C2-20 alicyclic hydrocarbon, aromatic ring or a structure represented by formula (C). R3 and R4 are independently and can be a hydrogen atom or a C1-6 alkyl group; S is 0 or 1; and Z is selected from R5 and R6 are independently and can be a hydrogen atom or a C1-12 hydrocarbon group.
