  • Publication number: 20170081481
    Abstract: The present invention relates to a process for drying particulate polymers, comprising the steps of: a) providing a particulate polymer comprising from 60 wt % to 90 wt % of at least one solvent based on the total weight of particulate polymer and solvent, b) mechanically predrying the particulate polymer to a content of the at least one solvent of from 20 wt % to 50 wt % based on the total weight of particulate polymer and solvent, wherein the mechanical predrying in step b) is carried out with a roller press, and c) end-drying the particulate polymer to a content of the at least one solvent of from 0 wt % to 15 wt % based on the total weight of particulate polymer and solvent, wherein the particulate polymer is a polymer comprising repeating units of formulae I, II and/or III The present invention further relates to a process for working up particulate polymers.

  • Publication number: 20160215105
    Abstract: Process for producing polyarylene ether beads from a polyarylene ether solution, comprising the steps of i) dividing the polyarylene ether solution into droplets, ii) transferring the droplets into a precipitation bath to form polyarylene ether beads in the precipitation bath which (A) comprises at least one aprotic solvent (component (1)) and at least one protic solvent (component (2)), (B) has a temperature of 0° C. to Tc, where the critical temperature Tc in [° C.] can be determined by the numerical equation Tc=(99?c)/0.61 in which c is the concentration of component (1) in the precipitation bath in [% by weight] and (C) has component (1) in concentrations of 5% by weight to cc, where the critical concentration cc in [% by weight] can be determined by the numerical equation cc=99?0.
