Document Type and Number:

WIPO Patent Application WO/2020/262255

Kind Code:

A1

Abstract:

The present invention provides: an LCP extruded film which is capable of enhancing the process tolerance during the production of a flexible laminate without excessively deteriorating the excellent basic properties of a liquid crystalline polymer; and the like. The present invention also provides: an LCP extruded film which enables the easy production of a flexible laminate that has high peel strength from a metal foil even under mild production conditions in comparison to prior art. An LCP extruded film 11 which contains an aromatic polyester-based liquid crystalline polymer that comprises, as monomer components, at least 6-hydroxy-2-naphthoic acid and a derivative thereof, and one or more substances selected from the group consisting of parahydroxybenzoic acid, terephthalic acid, isophthalic acid, 6-naphthalene dicarboxylic acid, 4, 4'-biphenol, bisphenol A, hydroquinone, 4, 4-dihydroxybiphenol, ethylene terephthalate and derivatives of these compounds; and this LCP extruded film 11 has a solubility in pentafluorophenol of 25% or more at 60°C.
