    摘要: Stabilized thermoplastic moulding compositions comprising (1) from 10 to 90 parts by weight of a polycarbonate, based on aromatic dihydroxy compounds; and (2) from 90 to 10 parts by weight of a mixture of (2.1) from 25 to 100 parts by weight of a graft copolymer of a monomer mixture of styrene, methyl methacrylate or acrylonitrile polymerized on a rubber; of (2.2) from 0 to 20 parts by weight of a butadiene polymer having a butadiene content of at least 5 parts by weight; and (2.3) from 0 to 75 parts by weight of a copolymer of styrene, .alpha.-methyl styrene, methyl methacrylate, acrylonitrile or methacrylonitrile; containing 0.01 to 3.0% by weight, based on the whole stabilized mixture, of at least one ester of phosphorous acid and an ortho- or para-substituted phenol or bisphenol, and a process for their production.
