Abstract:
Processes and compositions for cleaning mixing devices are disclosed that improve the production and quality of polycarbonate resins subsequently produced in the mixing device, while reducing the time needed for cleaning and/or change over. A cleaning mixture comprising polycarbonate resin pellets coated with an alkyl aryl sulfonate salt aqueous solution are used to purge the mixing device.
