Abstract:
A molding composition comprising:A) 40 to 99 parts by weight of at least one of aromatic polycarbonate or polyester carbonate; B) 0.5 to 60 parts by weight of graft polymer prepared from, B.1) 5 to 95 wt. % of one or more vinyl monomers, and B.2) 95 to 5 wt. % of one or more grafting backbones having a glass transition temperature of <10Â° C.; C) 0 to 45 parts by weight of at least one thermoplastic polymer selected from the group consisting of vinyl (co)polymers and polyalkylene terephthalates; D) 0.5 to 20 parts by weight of a phosphorus compound represented by formula (I) â€ƒin which R1, R2, R3 and R4 are mutually independently C1-C8 alkyl, optionally substituted by halogen, C5-C6 cycloalkyl, C6-C10 aryl or C7-C12 aralkyl, each optionally substituted by halogen or alkyl, or both, n are mutually independently 0 or 1, q are mutually independently 0, 1, 2, 3 or 4, N is 0.9 to 10, R5 and R6 mutually independently mean C1-C4 alkyl or halogen, Y means C1-C7 alkylidene, C1-C7 alkylene, C5-C12 cycloalkylene, C5-C12 cycloalkylidene, â€”Oâ€”, â€”Sâ€”, â€”SOâ€”, â€”SO2â€” or â€”COâ€”; and E) a fluorinated polyolefin in a form selected from the group consisting of one of, (i) a coagulated mixture of said fluorinated polyolefin and at least one component selected from the group consisting of component (A) and component (C), said coagulated mixture being formed by mixing an emulsion of said fluorinated polyolefin with at least one of an emulsion of component (A) or an emulsion of component (C), followed by coagulation thereof, or (ii) a precompound of said fluorinated polyolefin and at least one component selected from the group consisting of component (A), component (B) and component (C), said precompound being formed by dry mixing one of said fluorinated polyolefin in powder form and said fluorinated polyolefin in pelletized form with at least one of components (A), (B) or (C), or melt compounding the dry mixture.
