More Information
Summary:PURPOSE: A polycarbonate composition is provided to reduce the following yellowing of molded product produced in thermal curing and to ensure excellent optical characteristics. CONSTITUTION: A polycarbonate composition comprises melt polycarbonate, at least one of phosphine, and n-octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate, wherein the at least one of phosphine is a compound of chemical formula (I). In chemical formula (I), Ar1 and Ar2 are identically or differently, arbitrarily substituted aryl radicals, R' is arbitrarily substituted aryl radicals or chemical formulas (Ia) - (Ih).
