Document Type and Number:
WIPO Patent Application WO/2018/095191
Kind Code:
A1
Abstract:
Disclosed are a polycarbonate composition and method for preparing same, said composition comprising the following components in parts by weight: 35-70 parts of polycarbonate; 0-45 parts of graft copolymer; 8-30 parts of fire retardant; 5-45 parts of mineral filler; on the basis of the total weight of the polycarbonate composition, the weight content of elemental nickel is 1-100 ppm. In the present invention, by means of adding to the polycarbonate composition a nickel-containing compound having a low nickel content and reducing or avoiding the addition of other nickel-containing compounds, and controlling to within a range of 1-100 ppm the content of elemental nickel in the polycarbonate composition, the resulting polycarbonate composition, after being baked at 85°C for 200 h, has a chromatic aberration value of less than 8, a color level of 3 or higher, and excellent chromatic stability.
