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.
Claims7
A process for removing bubbles from a viscous polymer solution, comprising a step of subjecting the viscous polymer solution to a superatmospheric pressure at which gases contained in the bubbles are dissolved in the viscous polymer solution so as to remove the bubbles from the viscous polymer solution, wherein the superatmospheric pressure is generated by gas pressure.
A process for removing bubbles from a viscous polymer solution, comprising a step of subjecting the viscous polymer solution to a superatmospheric pressure at which gases contained in the bubbles are dissolved in the viscous polymer solution so as to remove the bubbles from the viscous polymer solution, wherein the superatmospheric pressure is generated mechanically with a plunger.
