Abstract
The present disclosure is direct to titanium dioxide-containing, polycarbonate-based thermoplastic compositions that contain epoxidized triacylglycerol. These compositions are suitable for reflectors. The compositions described in the present disclosure have an improved reflectance and a lower yellowness index as compared to reference compositions that do not contain epoxidized triacylglycerol. The epoxidized triacylglycerol may be in the form of epoxidized soybean oil.
