Abstract
A liquid-crystal polymer includes at least one repeating unit having a spiro structure, and the repeating unit occupies 1 mol % to 20 mol % of the liquid-crystal polymer. The liquid-crystal polymer is composed of the following repeating units: 1 mol % to 20 mol % of 10 mol % to 35 mol % of 10 mol % to 35 mol % of 10 mol % to50 mol % of and 10 mol % to 40 mol % of ARis wherein each of ring R and ring S is independently a Cring, ring R and ring S share a carbon atom, and each of Kand Kis independently a Cconjugated system. Each of AR, AR, AR, and ARis independently ARor AR—Z—AR.
