Aromatic polyketone and aromatic polyketone precursors and methods for their preparation with a 1,1'-binaphthyl-6,6'-ylene skeleton

摘要

PROBLEM TO BE SOLVED: To provide an aromatic polyketone where molecular chain extension is accomplished at the 6,6'-sites on a 2,2'-disubstituted-1,1'-binaphthylene skeleton.;SOLUTION: The aromatic polyketone, i.e. poly[(1,1'-binaphthyl-6,6'-ene)arylene dicarbonyl], is composed of recurring units each represented by formula(1)( wherein, R¹ and R² are each an alkoxy, or the like; R¹¹ to R²⁵ and R³¹ and R⁴¹ are each H, or the like ).;COPYRIGHT: (C)2005,JPO&NCIPI
