The invention relates to a process for the production of thermoplastic moulding compounds, in particular for the production of acrylonitrile-butadiene-styrene (ABS), wherein at least a first reagent () and a second reagent () of the thermoplastic moulding compounds are fed to a loop conduit () which comprises a static mixer (), wherein the reagents () are pressed in loops through the loop conduit () and passing the static mixer (), whereby the reagents () are dispersed to form a dispersion () in the static mixer (). The invention also relates to a thermoplastic moulding compound that is produced by the inventive process.

Process for the production of thermoplastic moulding compounds

The invention relates to a process for the production of thermoplastic moulding compounds, in particular ABS, wherein at least a first reagent () and a second reagent () of the thermoplastic moulding compounds are fed to a gear pump () which comprises a housing and at least a first gear wheel that is rotatable relative to the housing about a first axis, and a second gear wheel that is rotatable relative to the housing about a second axis, wherein a loop conduit () is provided, and wherein the reagents () are pressed in a loop through the loop conduit () and passing the gear wheels, whereby the reagents () are dispersed to form a dispersion () in the gear pump (). The invention also relates to a thermoplastic moulding compound that is produced by the inventive process.

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 materials based on acrylonitrile, styrene and butadiene

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.
