摘要： A manufacturing method for branched polycarbonate of the present invention comprises: a step of manufacturing a first raw material by mixing an aromatic dihydroxy compound, diarylcarbonate and 60-140 ppb (weight) of a catalyst with respect to the aromatic dihydroxy compound and reacting the same; a step of manufacturing a second raw material by mixing an aromatic dihydroxy compound, diarylcarbonate, a phosphorus based branching agent and 350-450 ppb (weight) of a catalyst with respect to the aromatic dihydroxy compound and reacting the same; and a step of performing melt polymerization on 100 parts by weight of the first raw material and 1-20 parts by weight of the second raw material. The branched polycarbonate manufactured by the manufacturing method has excellent thermal stability since catalyst content is low and exhibits excellent color stability and mobility.

摘要： A polycarbonate resin in the present invention is polymerized by a branching agent repregented by chemical formula 2, Mark-Houwink constant thereof is 0.4-0.60, and the concentration of a terminal hydroxyl group is 22% of total terminal groups. The branched polycarbonate resin remarkably decreases the concentration of hydroxyl groups so yellowness is improved and highly branched structure can be obtained. In the chemical formula 1, each of R1, R2, R3, and R4 is independently a substituted or non-substituted C1-10 alkyl group, a substituted or non-substituted C6-C18 aryl group, a C1-C10 alkyl group with halogen or a C1-C10 alkoxy group, or a C6-C18 aryl group with halogen or a C1-C10 alkoxy group substituent; W is a linear, branched, or cyclic saturated or unsaturated hydrocarbon group, saturated or unsaturated cyclic hydrocarbon substituent-containing hydro carbon group, an O or S-containing hydro carbon group, or S.
