Patent ID: 6919419

Claim:
An aromatic block polycarbonate resin of formula (6) prepared by polymerizing: a diphenol compound represented by formula (4), a diol compound represented by formula (5), and a halogenated carbonyl compound, wherein Ar 1 , Ar 2 , and Ar 3 are each a substituted or unsubstituted arylene group; R 17 and R 18 , which maybe the same or different, are each an acyl group, an alkyl group which may have a substituent, or an aryl group which may have a substituent; and m is an integer of 1 to 30, and OH—X—OH (5) wherein X is a substituted or unsubstituted bivalent aliphatic group, a substituted or unsubstituted bivalent cyclic aliphatic group, a substituted or unsubstituted bivalent aromatic group, a bivalent group prepared by bonding the bivalent groups, or a bivalent group represented by formula (1-a), (1-b), or (1-c): in which R 1 , R 2 , R 3 , and R 4 are each independently an alkyl group which may have a substituent, an aryl group which may have a substituent, or a halogen atom; a and b are each independently an integer of 0 to 4; c and d are each independently an integer of 0 to 3; and l is an integer of 0 or 1, and when l=1, Y is a straight-chain alkylene group having 2 to 12 carbon atoms, a substituted or unsubstituted branched alkylene group having 3 to 12 carbon atoms, a bivalent group comprising at least one alkylene group having 1 to 10 carbon atoms, and at least one oxygen atom and/or one sulfur atom, —O—, —S—, —SO—, —SO 2 —, —CO—, —COO—, in which Z 1 and Z 2 are each a substituted or unsubstituted bivalent aliphatic group, or a substituted or unsubstituted arylene group; R 5 , R 6 , and R 12 are each independently a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxyl group, or a substituted or unsubstituted aryl group; R 7 , R 8 , R 9 , R 10 , and R 11 are each independently a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxyl group, or a substituted or unsubstituted aryl group, and R 6 and R 7 may form together a carbon ring having 5 to 12 carbon atoms; l′ and l″ are each an integer of 0 or 1, and when l′=1 and l″=1, R 13 and R 14 are each an alkylene group having 1 to 4 carbon atoms; R 15 and R 16 are each independently a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group; e and g are each independently an integer of 0 to 4; f is an integer of 1 or 2; h is an integer of 0 to 20; and i is an integer of 0 to 2000, and wherein Ar 1 , Ar 2 , Ar 3 , R 17 , R 18 , X, and m are the same as those previously defined; and k and j represent the composition ratios, and 0<k/(k+j)<1.
