摘要：
Stabilized polymer composition comprising
A 10-90 parts by weight polycarbonate,
B 90-10 parts by weight of a mixture of
25-100 parts by weight of a graft copolymer obtained by
polymerizing a monomer mixture consisting of styrene, acrylonitrile, methylmethacrylate or a mixture of two or more of these compounds in the presence of a rubber, and
0-75 parts by weight of a copolymer of styrene, acrylonitrile, methylmethacrylate, or a mixture of two or more of these compounds
C 0.04-5.0 parts by weight stabilizer, per 100 parts by weight A and B jointly.
The stabilizer is a mixture of
C 1 0.01-1.0 parts by weight of one or more organic phosphites and/or phosphonites and
C 2 0.01 -2.0 parts by weight of at least one compound chosen from the group of
C 2 - 1 phenolic antioxidants, and
C 2 - 2 thio compounds,
as well as an effective quantity of a fatty acid, fatty acid ester, fatty acid amide, fatty acid salt or a mixture of two or more of these compounds.
