发明名称 Process for controlling the molecular weight of aromatic polycarbonates
摘要 Process for the preparation of aromatic polycarbonates by the interfacial technique wherein the molecular weight is controlled by adding an effective amount of metallic sulfites to the polymerization reaction. The metallic sulfites are exemplified by alkali metal sulfites, pyrosulfites and hyposulfites.
