POLYMERIC COMPOUND HAVING AROYLBIPHENYLENE SKELETON, AND POLYMER COMPOSITION FOR FORMATION OF THERMOSET FILM

摘要

Disclosed are: a polymeric compound which has excellent transparency, excellent heat resistance, a high refractive index and excellent solubility in various solvents, and which can be prepared into a solution having a low viscosity and excellent handling properties; a process for producing the polymeric compound; and a polymer composition containing the polymeric compound. Specifically disclosed are: an aroylbiphenyl compound represented by formula (1); a polymeric compound produced by using the aroylbiphenyl compound; and a polymer composition for forming a thermoset film, which comprises the polymeric compound as component (A) and a crosslinkable compound as component (B). In formula (1), X represents a halogen atom; and R1 represents a hydrogen atom or a group represented by formula (2a) or (2b). In formulae (2a) and (2b), R2 and R3 independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms.
