Patent ID: 6906122

Claim:
Blends containing A) 40 to 99 parts by wt. of aromatic polycarbonate and/or polyestercarbonate, B) 0.5 to 60 parts by wt. of a graft polymer, characterised in that the graft polymers B consist of B.1) 5 to 95 wt. % of one or more vinyl monomers and B.2) 95 to 5 wt. % of one or more particulate diene rubbers with a glass transition temperature of <10° C., which are prepared by emulsion polymensation, wherein an initiator system consisting of an organic hydroperoxide and ascorbic acid is used for graft polymerisation, C) 0 to 45 parts by wt. of at least one thermoplastic polymer, selected from the group consisting of thermoplastic vinyl (co)polymers and polyalkylene terephthalates and D) 0.1 to 30 parts by wt. of a phosphonate amine of the general formula (I) A 3-y -N—B y (I), in which A represents a group of the formula (IIa) or (IIb) R 1 and R 2 , independently, represent an unsubstituted or substituted C 1 -C 10 alkyl group or an unsubstituted or substituted C 6 -C 10 aryl group, R 1 and R 4 , independently, represent an unsubstituted or substituted C 1 -C 10 alkyl group or an unsubstituted or substituted C 6 -C 10 aryl group or R 3 and R 4 together represent an unsubstituted or substituted C 3 -C 10 alkylene group, y has the numerical value 0, 1 or 2 and B independently, represents hydrogen, an optionally halogenated C 2 -C 8 alkyl group, an unsubstituted or substituted C 6 -C 10 aryl group, E) 0 to 5 parts by wt. of a fluorinated polyolefin wherein the sum of the parts by wt. of all the blend components is 100.
