Title:
THERMOPLASTIC LIQUID CRYSTAL POLYMER FILM, LAMINATE, AND MOLDED BODY, AND PRODUCTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/218140
Kind Code:
A1
Abstract:
Provided are a thermoplastic liquid crystal polymer film, a laminate, and a molded body, which have both high heat resistance and productivity and have a wide process window when multilayering a wiring board. The thermoplastic liquid crystal polymer film is composed of a thermoplastic polymer capable of forming an optically anisotropic molten phase, wherein, in a profile of a storage elastic modulus obtained by measuring dynamic viscoelasticity, a rubbery plateau region exists at a temperature of 180 °C or higher, and the storage elastic modulus E' of the rubbery plateau region at 200-280 °C is 80 MPa or more.
