Abstract: A process produces a polymer composition (A) containing a styrene copolymer (a) and an impact modifier (b), comprising a copolymer (b1) as graft base and a graft (b2), where the steps of the process are: (1) providing a crosslinked copolymer (b1) made of: (b11) from 70 to 99.99% by weight of a conjugated diene or acrylate, (b12) from 0 to 29% by weight of another comonomer, (b13) from 0 to 10% by weight of crosslinking monomers, and (b14) from 0.01 to 0.7% by weight of a chain-transfer reagent; (2) applying, to the copolymer (b1), at least one graft (b2) comprising: (b21) from 65 to 95% by weight of a vinylaromatic monomer, (b22) from 5 to 35% by weight of acrylonitrile and/or methacrylonitrile, and (b23) from 0 to 30% by weight of monoethylenically unsaturated monomers, thus providing the impact modifier (b); (3) mixing the styrene copolymer (a) and the impact modifier (b), and thus leads to improved mechanical properties of the polymer composition (A).

Abstract: The invention relates to a process for the production of thermoplastic moulding compounds, in particular ABS, wherein at least a first reagent (11) and a second reagent (12) of the thermoplastic moulding compounds are fed to a gear pump (10) 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 (29) is provided, and wherein the reagents (11, 12) are pressed in a loop through the loop conduit (29) and passing the gear wheels, whereby the reagents (11, 12) are dispersed to form a dispersion (15) in the gear pump (10). The invention also relates to a thermoplastic moulding compound that is produced by the inventive process.

Abstract: The invention relates to a thermoplastic composition containing the components A and B and optionally the additional components C and D, the sum of which equals 100 wt. %. The molding compound consists of: a) 60 to 75 wt. % of one or more styrene copolymers A, b) 25 to 40 wt. % of one or more graft copolymers B, c) 0 to 15 wt. % of a rubber C which is different from component B, and d) 0 to 5 wt. % of one or more additives D. The composition contains 0.2 to 3.0 wt. %, based on the total weight of the components A to D, of oligomers, can be readily processed, and leads to scratch-resistant molded parts.

Abstract: The present invention relates to a process for the production of styrene graft copolymers comprising addition and graft copolymerization of styrene monomers A1 and vinyl cyanide monomers A2 to a graft base B where the ratio by mass of A1 to A2 in the monomer feed at the end of the monomer feed time is lower than the ration by mass integrated over the entire monomer feed time. The present invention further relates to a graft copolymer obtainable by a process according to the invention, a molding composition comprising such a graft copolymer, and a molding obtained from such a molding composition.
