THERMOPLASTIC LIQUID CRYSTAL POLYMER AND FILM OF SAME

WIPO Patent Application WO/2018/181222

A1

Provided are: a thermoplastic liquid crystal polymer which is able to be decreased in the dielectric loss tangent in a high frequency range; and a film of this thermoplastic liquid crystal polymer. This thermoplastic liquid crystal polymer contains repeating units represented by formulae (I), (II), (III) and (IV); the molar fraction of the total amount of the repeating unit represented by formula (I) and the repeating unit represented by formula (II) relative to the total amount of all repeating units in the thermoplastic liquid crystal polymer is 50-90% by mole; and the molar ratio of the repeating unit represented by formula (III) to the repeating unit represented by formula (IV) is from 23/77 to 77/23.
