Patent ID: 7071285

Claim:
An aromatic polycarbonate resin, comprising: a structural unit of formula (1); and a structural unit of formula (2), with the relationship between the composition ratios being 0<k/(k+j)<1 when the composition ratio of said structural unit of formula (1) is k and that of said structural unit of formula (2) is j: wherein R 1 and R 2 , which may be the same or different, are each an acyl group, an alkyl group having 1 to 6 carbon atoms, which may have a substituent, or an aryl group which may have a substituent; and Ar 1 , Ar 2 , and Ar 3 are each a substituted or unsubstituted arylene group; wherein a and b are each independently an integer of 1 to 4; and R 3 and R 4 are each independently a halogen atom, an alkyl group having 1 to 6 carbon atoms, which may have a substituent, an alkoxyl group having 1 to 6 carbon atoms, which may have a substituent, or an aryl group which may have a substituent, and R 3 and R 4 may each be the same or different when a and b are each an integer of 2, 3 or 4; wherein an amount of said structural unit of formula (2) is 58 to 60 mole percent; and wherein an amount of said structural unit of formula (1) is 40 to 42 mole percent.
