Patent ID: 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.
