<p>A branched polycarbonate having a branched structure derived from a branching agent such as 1,1,1-tris(4-hydroxyphenyl)ethane, mainly comprising repeating units represented by formulae (I) and (II); being terminated with tribromphenoxy or the like group, having a viscosity-average molecular weight of 10,000 to 50,000, and containing 0.1 to 2.0 mole% of the branched structure and at most 10 mole% of the repeating units (II). The polycarbonate is excellent in flame retardance, mechanical properties, and melting behaviors such as blow moldability. <CHEM> <IMAGE></p> |
