This presentation will focus on the history and evolution of the Lexan polycarbonate manufacturing process and its tie to product performance and applications. Originally based on interfacial phosgenation processes, polycarbonate is also produced by melt transesterification processes. The key process features and a comparison of the two processes will be discussed.
Finally, as the market for polycarbonate matures, SABIC Innovative Plastics has increased its focus on producing novel Lexan polycarbonate copolymers with enhanced properties for demanding product applications. This has resulted in new process challenges and breakthroughs for commercial production. An example of a Lexan polycarbonate co-polymer process will be reviewed.
