摘要：
A fluorine-containing dicarboxylic acid represented by formula (1), wherein n represents an integer of 1-4, and the two carboxylic groups are not adjacent to each other on the aromatic ring. It is possible to obtain a linear polymer compound by reacting the fluorine-containing dicarboxylic acid with a comonomer (e.g., diaminodiol). By thermal cyclization, this linear polymer compound can be converted into another polymer compound having superior characteristics.
