Process for colored polycarbonate-polyester compositions with improved weathering |
摘要 |
A process for preparing a high gloss retention resin molding formulation comprising a polyester resin and a polycarbonate resin where the process comprises the steps of selecting a desirable colorant which is stable at molding temperatures and has desirable color retention properties when subjected to weathering, determining an optimized concentration of the colorant for maximizing gloss retention properties of the selected colorant by performing weathering test at differing concentrations of the colorant, and optionally determining a suitable gloss enhancing.
