<P>PROBLEM TO BE SOLVED: To provide a phosphorus-containing polycarbonate resin capable of suppressing bleed-out when used in a composition and having excellent balance of hydrolysis resistance and flame retardancy, and a composition containing the phosphorus-containing polycarbonate resin. <P>SOLUTION: The phosphorus-containing polycarbonate resin has a repeating unit of a structure represented by formula (A) and a specific repeating unit. The composition contains the same. In the formula, R<SP POS="POST">1</SP>, R<SP POS="POST">2</SP>, R<SP POS="POST">3</SP>and R<SP POS="POST">4</SP>each represent nitro, cyano, 1-6C alkyl which may have a substituent, 1-6C alkenyl which may have a substituent, 1-6C alkyloxy which may have a substituent, 6-18C aryl which may have a substituent, or 6-18C aryloxy which may have a substituent; p, q, r and s represent the numbers of R<SP POS="POST">1</SP>, R<SP POS="POST">2</SP>, R<SP POS="POST">3</SP>and R<SP POS="POST">4</SP>on the benzene rings, respectively, p and q are each an integer of 0-5, r and s are each an integer of 0-4; and R<SP POS="POST">5</SP>represents H or 1-6C alkyl. <P>COPYRIGHT: (C)2013,JPO&INPIT |
