ABSTRACT:
In a process for removing bubbles from viscous polymer solutions (P) in which the content of dissolved gases lies below the saturation limit, the viscous polymer solution (P) is subjected to a superatmospheric pressure. The superatmospheric pressure is such that the gases contained in the bubbles of the polymer solution (P) dissolve.
