Polycarbonate moulding compounds modified with a graft polymer and containing phosphorus compounds of formula (I): (see formula I) wherein R1, R2, R3 and R4 independently of one another are optionally halogen- substituted C1-C8-alkyl or optionally halogen-substituted and/or alkyl-substituted C5-C6--cycloalkyl, C6-C10-aryl or C7-C12-aralkyl, n independently of one another are 0 or 1, q independently of one another are 0, 1, 2, 3 or 4, N is 0 to 10, R5 and R6 independently of one another are C1-C4-alkyl or halogen, and Y is C1-C7-alkylidene, C1-C7-alkylene, C5-C12-cycloalkylene, C5-C12-cyclo--alkylidene, -O-, -S-, -SO-, -SO2- or -CO-, and fluorinated polyolefins in the form of a mixture with polyalkyl (meth)acrylates.

La présente invention concerne des matières à mouler polycarbonate modifiées avec un polymère greffé, contenant des composés de formule (1) dans laquelle: R?1¿, R?2¿, R?3¿ et R?4¿ sont indépendamment les uns des autres alkyle en C¿1?-C¿8? éventuellement substitué par halogène, cycloalkyle en C¿5?-C¿6?, aryle en C¿6?-C¿10? ou aralkyle en C¿7?-C¿12? respectivement éventuellement substitué par halogène et/ou alkyle; n vaut indépendamment 0 ou 1; q vaut indépendamment 0, 1, 2, 3 ou 4; N vaut de 0 à 10; R?5¿ et R?6¿ représentent indépendamment l'un de l'autre alkyle en C¿1?-C¿4? ou halogène; Y est alkylidène en C¿1?-C¿7?, alkylène en C¿1?-C¿7?, cycloalkylène en C¿5?-C¿12?, cycloalkylidène en C¿5?-C¿12?, -O-, -S-, -SO-, -SO¿2?- ou -CO-, lesdites matières comprenant également des polyoléfines fluorées se présentant sous la forme d'un mélange avec des polyalkyl(méth)arylates.
