Abstract
Branched polycarbonates are prepared by the use as a branching agent, in an interfacial polycarbonate formation reaction, of a 2',4,4"-m-terphenyltriol, preferably the unsubstituted compound. Said branched polycarbonates have properties which are advantageous for blow molding and the like.
