To provide new phosphorus-containing compounds that are derived from phosphorus-containing diphenols and are raw materials for synthesizing polyamide and phosphorus-containing polyamides formed by using them.
A series of new phosphorus-containing compounds represented by formula (I) are synthesized and polyamides are also synthesized using the compounds (in the formula, R1 to R4 are each selected from the group consisting of a hydrogen atom, 1C-6C alkyl, 1C-6C alkoxy, 1C-6C haloalkyl, 3C-7C cycloalkyl, -CF3, -OCF3 and a halogen atom; A indicates -O- or -OOC-; Q is selected from the group consisting of -NO2, -NH2 and the like; and m indicates an integer of 1 to 4).
