Document Type and Number:

WIPO Patent Application WO/2016/197907

Kind Code:

A1

Abstract:

Disclosed is a polycarbonate composition, comprising the following components in parts by weight: a, 30-80 parts of a polycarbonate, b, 8-50 parts of a graft polymer, c, 5-25 parts of a fire retardant and d, 0-10 parts of other auxiliaries; wherein the sum of the parts by weight of the four components of a, b, c and d is 100 parts. In the present invention, when the compound total mass of the transition element and the alkaline-earth metal added into the polycarbonate composition formulation based on the total weight of the polycarbonate composition is selected to be larger than or equal to 10 ppm and less than or equal to 600 ppm and the compound molar ratio of the transition element to the alkaline-earth metal is adjusted to 0.1-1, the long-term thermo-oxidative aging performance and the weather resistance of the polycarbonate composition can be significantly improved, and the polycarbonate composition is particularly suitable for occasions with high use environment requirements.
