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.
