Abstract
A flame retardant, thermoplastic molding composition is disclosed. The composition contains A) at least one of aromatic polycarbonate and polyester carbonate, B) polyalkyl (alkyl)acrylate, C) a graft polymer the molecular structure of which is substantially free of units derived from styrene, butadiene and acrylonitrile, D) at least one organic phosphoric acid ester, E) an optional anti-drip agent, and F) optionally at least one polymer additive. The composition is characterized in its good property profile especially weld line strength, resistance to chemicals, elongation at break, thermal stability and melt flowability.
Claims19
A thermoplastic molding composition containing
- A) at least one member selected from the group consisting of aromatic polycarbonate and polyester carbonate,
- B) polyalkyl (alkyl)acrylate,
- C) a graft polymer the molecular structure of which is substantially free of units derived from styrene, butadiene and acrylonitrile,
- D) at least one organic phosphoric acid ester, and
- E) an optional anti-drip agent, and
- F) optionally at least one polymer additive,
- wherein the total content of residual monomers of styrene, acrylonitrile and butadiene and structural units derived from such monomers does not exceed 0.5% relative to the total weight of the composition.
