Title:
THERMOPLASTIC RESIN AND OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2023/074471
Kind Code:
A1
Abstract:
The present invention provides a thermoplastic resin that can provide balance among a high refractive index, high heat resistance, and low birefringence, and also provides an optical member that contains this thermoplastic resin. The thermoplastic resin according to the present invention contains a repeat unit represented by formula (1). (In the formula, the rings Z (which may be the same or may differ) each represent a polycyclic aromatic hydrocarbon in which at least three benzene rings are bonded; R1, R2, R3, and R4 each independently are a hydrogen atom or a halogen atom or represent a C1-C20 substituent which may contain an aromatic group; L1 and L2 each independently represent a divalent linking group; j and k each independently represent an integer equal to or greater than 1; m and n each independently represent 0 or 1; and W is at least one selection from the group represented by formula (2) and formula (3).) (In the formula, X represents a divalent linking group.)
