Abstract: Usually, polycarbonate polymerization is limited by the rate at which inhibitory byproducts, such as phenol and salicylate, can be removed from the reaction. To facilitate the removal of volatile reaction byproducts from the reaction as polymerization occurs, the present invention provides a spray mist reactor. The formation of a spray mist polymerization reaction allows for the creation of an enormous surface area for exchange of volatile byproducts. The present invention is applicable to polymerization of polycarbonate and its copolymers starting with monomers or oligomers. The invention may be used to increase throughput and minimize initial investment for a give melt process, especially the fast reacting bis(methylsalicylate) carbonate process.
