Process for the production of polycarbonate

A process for the production of an aromatic polycarbonate, comprising the steps of:

• (a) preparing a polycarbonate having free terminal OH groups by a melt transesterification process from an aromatic dihydroxy compound and a carbonic acid diester;
• (b) adding to the polycarbonate having free terminal OH groups, a sufficient amount of an end-capping agent of the following formula for capping the free terminal —OH groups of the polycarbonate, thereby forming a polycarbonate with an increased level of capped or blocked hydroxy groups:
• 9
• wherein R1 is a methoxy, ethoxy, propoxy, butoxy, phenyl, phenoxy, benzyl, or benzyloxy and R2 is selected from the group consisting of C1-C30 alkyl, C1-C30 alkoxy, C6-C30 aryl, C6-C30 aryloxy, C7-C30 aralkyl, and C6-C30 aralkyloxy.
