PROBLEM TO BE SOLVED: To provide polycarbonate molding compositions having chemical resistance and heat stability (low yellowing and low degradation properties under heat stress).SOLUTION: Molding compositions comprise polycarbonates, graft polymers and optionally further additives, comprise components with low free bisphenol A content, and have good heat stability in addition to high chemical stability (in particular a low tendency towards yellowing and a low tendency towards degradation under a heat load). In a specific flameproofed embodiment, the after-burn time in the UL 94 Standards is reduced.SELECTED DRAWING: None 【課題】耐薬品性、熱安定性（熱応力下での低い黄変性及び低い分解性）を有するポリカーボネート成形用組成物を提供する。【解決手段】ポリカーボネート、グラフトポリマー、および任意に更なる添加剤を含んでなる成形用組成物であって、遊離ビスフェノールＡ含量の低い成分を含んでなり、高い化学安定性だけでなく良好な熱安定性（特に、熱負荷下での低い黄変傾向および低い分解傾向）も有する。また、１つの特定の難燃性の態様では、ＵＬ９４規格における接炎後残炎時間が短縮される。【選択図】なし
