Abstract: Processes and compositions for cleaning mixing devices are disclosed that improve the production and quality of thermoplastic polymer resins subsequently produced in the mixing device, while reducing the time needed for cleaning and/or change over. A cleaning mixture comprising polymeric resin pellets having a Rockwell R hardness of 85 to 140 externally coated with an aqueous solution containing sulfonate salts, alkyl aryl sulfonate salts, alkyl sulfate salts, C6 to C36 carboxylic acid salts, or mixtures thereof, is used to purge the mixing device. The surfactant salt is present in the aqueous solution at 0.2 to 30 wt % of the solution, the aqueous solution having a pH of 6.0 to 9.0.

Abstract: The disclosure concerns compositions and methods to improve remote phosphor optical properties in polycarbonate. One method includes combining a phosphor component and a polycarbonate component to form a phosphor-polycarbonate composition; and at a fixed phosphor concentration, combining the phosphor-polycarbonate composition with a diffusing agent comprising polytetrafluoroethylene (PTFE), wherein the diffusing agent diffuses light, and wherein the phosphor-polycarbonate composition exhibits an increase in chromaticity coordinate (CIEx) as determined by CIE 1931 or increase in CIE 1976 (u′,v′) of at least about 5% relative to a substantially similar reference composition in the absence of PTFE. Also described are methods to increase yield and reduce product accumulation of an extruded thermoplastic polycarbonate composition through the mixing of PTFE with a phosphor-polycarbonate (PCP) to form a PCP-PTFE component as well as a method forming a phosphor-polycarbonate master batch (PPCMB) composition, and during extrusion, adding PTFE to the PPCMB composition to form a PPCMB-PTFE composition.
