Abstract: The invention relates to a method for producing polyarylene ether beads from a polyarylene ether solution, having the steps of i) separating the polyarylene ether solution in a separating device which is vibrated at a frequency ranging from 10 to 1400 Hz, thereby obtaining drops, and ii) transporting the drops into a precipitation bath, thereby forming polyarylene ether beads in the precipitation bath. The precipitation bath (A) contains at least one aprotic solvent (component (1)) and at least one protic solvent (component (2)), (B) has a temperature of 0 °C to T
c , the critical temperature T
c in [°C] being determined by the numerical equation T
c = (77 - c)/0.58, in which c is the concentration of the component (1) in the precipitation bath in [wt.%], and (C) has the component (1) in concentrations of 5 wt.% to c
c , the critical concentration c
c in [wt.%] being determined by the numerical equation c
c = 77 - 0.58 * T, in which T is the temperature in the precipitation bath in [°C], wherein the wt.% in each case is based on the sum of the wt.% of the component (1) and the component (2) in the precipitation bath.Abstract translation: 本发明涉及一种由聚芳醚溶液制备聚亚芳基醚珠粒的方法，包括以下步骤：i）将分散装置中的聚亚芳基醚溶液除以10-1400Hz的频率振动得到液滴，ii （A）包含至少一种非质子溶剂（组分（1））和至少一种质子溶剂（组分（2）），（B）具有至少一种质子溶剂 温度为0℃至Tc，其中[℃]中的临界温度Tc可以通过数学方程式Tc =（77-c）/0.58确定，其中c是组分（1）中的浓度 沉淀浴中的[重量％]和（C）的组分（1）的浓度为5重量％〜cc，其中临界浓度cc（重量％）可以通过数学式cc = 77-0.58 * T，其中T是沉淀浴中的温度[℃]，其中 重量百分比分别基于沉淀浴中组分（1）和组分（2）的重量百分比之和。

Abstract: The invention relates to a method for producing a turbine wheel for an exhaust gas turbocharger by means of metal injection molding, comprising the following steps: (a) providing a feedstock containing a metal powder and a binder material, (b) providing a tool, which comprises a negative mold of the turbine wheel to be produced, for metal injection molding of the turbine wheel, (c) introducing a rotationally symmetrical core composed of the binder material into the negative mold of the tool provided in method step (b) and orienting the core so that the core is oriented symmetrically to the rotational axis of the turbine wheel to be produced, (d) producing a green body by means of metal injection molding of the feedstock provided in method step (a) around the core, (e) performing a binder removal step to remove the binder from the green body to obtain a molded body in the form of the turbine wheel, and (f) sintering the molded body.
