  • Patent number: 9127132
    Abstract: Sulfonated block copolymers (SBCs) are coagulated from SBC solutions in one or more organic solvents, including reaction mixtures obtained in the sulfonation process, by a process in which the SBC solution is ejected into or onto water provided that no steam is added to the SBC solution prior to ejection and provided that the ejection velocity as well as the water temperature and convection are controlled and balanced. The coagulation process is easy to implement and avoids or at least diminishes problems due to foaming and the formation of micro dispersions of the SBC which cannot be separated successfully or easily by conventional filtration or centrifuging.

The partially substituted polymer dopant may serve as a dopant upon synthesis of the conducting polymer or upon additional doping of the synthesized polymer. Compared to a conventional monomer dopant, the polymer dopant does not emit low-molecular-weight material, and has higher solubility. Further, compared to a polymer dopant having a substituent such as a sulfonic acid group throughout, the synthesized conducting polymer can have superior mechanical properties and maximum conductivity.
