Abstract
Thermoplastic moulding composition comprising at least 2 components chosen from the group consisting of aromatic poly(ester)carbonates, graft polymers of one or more vinyl monomers on one or more graft bases having a glass transition temperature of <10° C., thermoplastic vinyl (co)polymer and polyalkylene terephthalate and 0.5 to 20 parts by wt. phosphorus compound of the general formula (I).

Thermoplastic moulding composition comprising at least 2 components chosen from the group consisting of aromatic poly(ester)carbonates, graft polymers of one or more vinyl monomers on one or more graft bases having a glass transition temperature of <10° C., thermoplastic vinyl (co)polymer and polyalkylene terephthalate and 0.5 to 20 parts by wt. phosphorus compound of the general formula (I)
- wherein
- X and Y represent a mono- or polynuclear aromatic radical having 6 to 30 C atoms, and X and Y differ from one another,
- R1, R2, R3, R4 and R5 independently of one another denote optionally halogenated C1-C8-alkyl, or C1-C6-cycloalkyl, C6-C20-aryl or C7-C12-aralkyl, in each case optionally substituted by halogen and/or C1-C4-alkyl,
- Z denotes 0.05 to 0.95, preferably 0.15 to 0.85,
- n independently of one another denote 0 or 1, preferably 1, and N denotes 0.5 to 30
- as a further component.
Thermoplastic moulding compositions comprising
- A. 5 to 95 parts by wt. aromatic polycarbonate or polyester-carbonate,
- B. 0.5 to 60 parts by wt. graft polymer of
- B.1 5 to 95 wt. % of one or more vinyl monomers on
- B.2 5 to 95 wt. % of one or more graft bases having a glass transition temperature of <−10° C.,
- C. 0 to 50 parts by wt. thermoplastic vinyl (co)polymer and/or polyalkylene terephthalate
- D. 0.5 to 20 parts by wt. of a phosphorus compound of the formula (I)
- wherein
- X and Y represent a mono- or polynuclear aromatic radical having 6 to 30 C atoms, and X and Y differ from one another,
- R1, R2, R3, R4 and R5 independently of one another denote optionally halogenated C1-C8-alkyl, or C5-C6-cycloalkyl, C6-C20-aryl or C7-C12-aralkyl, in each case optionally substituted by halogen and/or C1-C4-alkyl,
- z denotes 0.05 to 0.95, preferably 0.15 to 0.85
- n independently of one another denote 0 or 1, preferably 1, and
- N denotes 0.5 to 30
- E. 0.05 to 5 parts by wt. fluorinated polyolefin,
- the sum of the parts by wt. of all the moulding composition components being 100.
