    摘要: A phosphorus compound represented by the formula (I): wherein R1 and R2 are, the same or different, a hydrogen atom, a straight or branched-chain alkyl group having 1 to 6 carbon atoms or an aryl group having 6 to 12 carbon atoms which may be optionally substituted for an alkyl group having 1 to 4 carbon atoms, R3, R4, R5, R6 and R7 are, the same or different, a hydrogen atom or an aryl group having 6 to 12 carbon atoms which may be optionally substituted for an alkyl group having 1 to 4 carbon atoms, or R3 and R4, R4 and R5, R5 and R6 or R6 and R7 may form a 6 membered ring with carbon atoms wherein these groups bond a benzene ring provided that R3, R4, R5, R6 and R7 are not hydrogen atoms at the same time.
