  • Liquid-crystal polymer, laminated material, liquid-crystal polymer solution, and method of forming liquid-crystal polymer film
    Patent number: 11866632
    Abstract: Liquid-crystal polymer is composed of the following repeating units: 10 mol % to 35 mol % of 10 mol % to 35 mol % of 10 mol % to 50 mol % of and 10 mol % to 40 mol % of 10 mol % to 40 mol % of or a combination thereof. Each of AR1, AR2, AR3, and AR4 is independently AR5 or AR5-Z-AR6, in which each of AR5 and AR6 is independently or a combination thereof, and Z is —O—, or C1-5 alkylene group. Each of X and Y is independently H, C1-5 alkyl group, CF3, or wherein R2 is H, CH3, CH(CH3)2, C(CH3)3, CF3, or n=1 to 4; and wherein R1 is C1-5 alkylene group.

  • Liquid-crystal polymer, laminated material, liquid-crystal polymer solution, and method of forming liquid-crystal polymer film
    Patent number: 11572438
    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 % to 50 mol % of and 10 mol % to 40 mol % of AR1 is wherein each of ring R and ring S is independently a C3-20 ring, ring R and ring S share a carbon atom, and each of K1 and K2 is independently a C5-20 conjugated system. Each of AR2, AR3, AR4, and AR5 is independently AR6 or AR6—Z—AR7.
