Method for producing branched polycarbonates

In the process of producing branched polycarbonates by melt transesterification from at least one diphenol, diaryl carbonate and a branching agent, and in the optional presence of a catalyst, at temperatures between 80 to 400° C. and at pressures between 1 and 0.01 mbar, the improvement comprising using as branching agent, about 0.05 to 2 moles per 100 moles of said diphenol, at least one member selected from the group consisting of (i) an aliphatic alcohol conforming to

• wherein R′ is a single bond, a linear C1-36-alkylene or a branched C3-36-alkylene and R and R″ independently denote H, linear C1-36-alkyl, branched C3-36-alkyl or R′″-OH where R′″ is a linear C1-36-alkylene or a branched C3-36-alkylene, and n is 2,3,4 or 5, and (ii) the ether of said (i) which is formed by self-condensation.
