Abstract: A method of preparing a polycarbonate composition in a polymerization system that includes a monomer mixing unit, an oligomerization section, and a polymerization section. The method includes melt polymerizing a dihydroxy compound with a diaryl carbonate compound in the presence of a quaternary phosphonium catalyst to produce the polycarbonate composition having a phosphorus-containing byproduct of at least one of the quaternary phosphonium catalyst or of the diaryl carbonate compound. The method further includes recycling the phosphorus-containing byproduct into the monomer mixing unit of the polymerization system and removing the polycarbonate composition from the polymerization system. The recycle stream has a phosphorus concentration of greater than or equal to 40 parts per million by weight.

Abstract: In an embodiment, a polycarbonate polymerization process comprises interfacially polymerizing a carbonate compound and dihydroxy compound in the presence of an interfacial catalyst to form a polycarbonate and adding a viscosity reducing agent and a transesterification catalyst to polycarbonate upstream of a first filter to form an adjusted polycarbonate. The first filter can be replaced with a replacement filter and the adjusted polycarbonate can be introduced to the replacement filter. The flow can be diverted to a replacement filter. The process further comprises reducing the addition rate of the viscosity reducing agent and the transesterification catalyst until the addition rate is 0 mol/hr.
