Abstract:
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 j and that of said structural unit of formula (2) is ##STR36##wherein a, b, c and d are each independently an integer of 0 to 4; n is an integer of 0 or 1; and R.sup.1, R.sup.2, R.sup.3 and R.sup.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.sup.1, R.sup.2, R.sup.3 and R.sup.4 may each be the same or different when a, b, c and d are each an integer of 2, 3 or 4; ##STR37##wherein R.sup.5 is a hydrogen atom, an alkyl group which may have a substituent, or an aryl group which may have a substituent; Ar.sup.1 is an aryl group which may have a substituent; and Ar.sup.2 and Ar.sup.3 are each an arylene group which may have a substituent.
