| titleOfInvention | CONTINUOUS METHOD FOR OBTAINING BRANCHED POLYCARBONATE |
| abstract | SUBSTANCE: invention relates to a method for continuous production of branched polycarbonate, comprising (A) a stage of obtaining a low molecular weight polycarbonate with a number average molecular weight of 1000-10000 from an aromatic dihydroxy compound and a carbonic diester by transesterification; (B) a step of adding and mixing the polyfunctional compound with a low molecular weight polycarbonate in a liquid state; and (C) a step of subsequently carrying out the polymerization reaction until the melt index of the low molecular weight polycarbonate exceeds 10 g / 10 min and the branching index becomes at least 14 to form a branched polycarbonate. |
