Polycarbonate resin and molded article thereof

A polycarbonate resin comprising a unit (A) represented by the following formula:

• and a unit (B) represented by the following formula:
• [In the formula (B), W is a single bond or selected from the following formulas (W):
• (Ri and R2 are each independently a hydrogen atom, fluorine atom, chlorine atom, bromine atom, iodine atom, alkyl group having 1 to 9 carbon atoms, alkoxy group having 1 to 5 carbon atoms, aryl group having 6 to 12 carbon atoms, alkenyl group having 2 to 5 carbon atoms or aralkyl group having 7 to 17 carbon atoms. R1 and R2 may be bonded together to form a carbon ring or heterocyclic ring. R3 and R4 are each independently a hydrogen atom, fluorine atom, chlorine atom, bromine atom, iodine atom, alkyl group having 1 to 9 carbon atoms, alkoxy group having 1 to 5 carbon atoms or aryl group having 6 to 12 carbon atoms. R5 is an alkylene group having 1 to 9 carbon atoms. a is an integer of 0 to 20, and b is an integer of 1 to 500.)] as the main recurring units, the molar ratio of the unit (A) to the unit (B) being 5/95 to 95/5.
