Process for the production of an object from an ABS-polymer composition

摘要

The invention relates to a process for the production of an object from a granular ABS polymer composition, said composition comprising a mixture of I 10-98 parts by weight of one or more graft copolymers obtained by polymerizing a mixture of one or more unsaturated nitriles and one or more vinylaromatic compounds in the presence of a rubber. II 2-90 parts by weight of a copolymer of one or more unsaturated nitriles and one or more vinylaromatic compounds, and III 0-20 parts by weight of one or more additives, wherein the polymer composition is melted, homogenized, and extruded or injection molded into an object. To improve the flow properties of the mixture introduced into the processing equipment and the throughput of this equipment the invention is characterized in that the ratio between the average particle size (by weight) of the copolymer II to the average particle size (by weight) of the graft copolymer I exceeds 1.5.
