Abstract: A method of determining degradation of a thermoplastic when exposed to light and heat includes illuminating the thermoplastic with a desired wavelength of light at a desired irradiance while maintaining the ambient air surrounding the thermoplastic at a desired temperature. The method is useful to measure the discoloration rate of transparent, translucent and opaque thermoplastics such as polycarbonates, the discoloration rate being determined by transmission or reflectance spectra of transmitted or reflected white light through or from the thermoplastic.

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.
