Abstract:
An aromatic polycarbonate resin having a repeat unit of formula (I): ##STR58## wherein n is an integer of 5 to 5000; Ar.sup.1 and Ar.sup.5 may be the same or different, and represent a bivalent aromatic hydrocarbon group which may have a substituent or a bivalent heterocyclic group which may have a substituent; Ar.sup.2, Ar.sup.3, Ar.sup.4 and Ar.sup.6 each may be the same or different, and represent an aromatic hydrocarbon group which may have a substituent, or a heterocyclic group which may have a substituent; and X is a bivalent aliphatic group, a bivalent cyclic aliphatic group, or ##STR59## in which R.sup.1 and R.sup.2 are each independently an alkyl group which may have a substituent, an aromatic hydrocarbon group which may have a substituent, or a halogen atom; l and m are each independently an integer of 0 to 4; and p is an integer of 0 or 1, and when p=1, Y is a straight-chain, branched or cyclic alkylene group having 1 to 12 carbon atoms, --O--, --S--, --SO--, --SO.sub.2 --, ##STR60## in which Z is a bivalent aliphatic hydrocarbon group; a is an integer of 0 to 20; b is an integer of 1 to 2000; and R.sup.3 and R.sup.4 are each independently an alkyl group which may have a substituent or an aromatic hydrocarbon group which may have a substituent.
