| titleOfInvention | Melt polymerization polycarbonate quenching |
| abstract | In an embodiment: a melt polymerization process comprises: melt polymerizing reactants in at least two polymerization units, in the presence of a first catalyst composition and a second catalyst composition to form polycarbonate, wherein the first catalyst composition and the second catalyst composition comprise an alpha catalyst; wherein the melt polymerizing comprises: adding the first catalyst composition to the polycarbonate, adding a first quencher composition to the polycarbonate downstream of adding the first catalyst composition, adding the second catalyst composition to the polycarbonate downstream of adding a first quencher composition; filtering the polycarbonate; and directing the polycarbonate to an extruder. |
