The invention relates to thermoplastic ABS molding compositions comprising components A) and B): A) from 5 to 80% by weight of a graft polymer A) having bimodal particle size distribution; and B) from 20 to 95% by weight of a thermoplastic polymer B) having a viscosity number VN of from 50 to 120 ml/g. The invention further relates to a process for the preparation of graft copolymer A and to the graft copolymer made by that process.

ABS product with improved fire retardancy

The invention relates to thermoplastic moulding materials based on acrylonitrile-butadiene-styrene, comprising a SAN-polymer matrix and a graft copolymer, structured from an agglomerated butadiene rubber-graft base and a SAN-graft envelope. The agglomerated graft base has a bimodal particle size distribution of a fraction x) of non-agglomerated particles having a d50-value in the range from 80 to 120 nm and a fraction y) of agglomerated particles having a d-value in the range from 350 to 550 nm and a polydispersity U of less than 0.28. The invention further relates to a method for producing the graft copolymer, wherein an acrylate copolymer having a polydispersity U of less than 0.27 and a d50-value of 100 to 150 nm is used for agglomeration. The invention further relates to the use of thermoplastic moulding materials for producing moulded parts.

Thermoplastic moulding compositions for metal plated articles with improved resistance against repeated impact

The invention relates to thermoplastic molding materials based on acrylonitrile-butadiene-styrene, comprising a SAN-polymer matrix and a graft copolymer, structured from an agglomerated rubber-graft base and a SAN-graft envelope. The basis of the graft base is a diene rubber having a vinyl-aromatic ratio of 10.5 to 24.5 wt %. The agglomerated graft base has a bimodal particle size distribution of a fraction x) of non-agglomerated particles having a d-value in the range from 80 to 120 nm and a fraction y) of agglomerated particles having a d50-value in the range of 350 to 550 nm and a polydispersity U of less than 0.28. The invention further relates to a method for producing the graft copolymer, wherein an acrylate copolymer having a polydispersity U of less than 0.27 and a d50-value of 100 to 150 nm is used for agglomeration. The invention further relates to the use of thermoplastic molding materials for producing molded parts.
