Branched polycarbonate having branching parameter and degree of branching

摘要

A branched polycarbonate having (1) an intrinsic viscosity of 0.3 to 2 dl/g, (2) a branching parameter of 0.05 to 0.9, (3) a degree of branching of 0.2×10.sup.-4 and optionally (4) a taking-off parameter of 2.5 to 20. The branched polycarbonate is useful as a raw material for blow- moldings.
