Zusammenfassung:	A static devolatilization device for polymer containing liquid is provided to generate the mixture of liberated gas and low-gas polymer during foaming the liquid. In the static devolatilization device(1) for polymer containing liquid(7) for devolatilizing polymers by expanding the liquid pressurized in a container(10), a devolatilized polymer discharge pump(3) is positioned at a base portion of a sump region. An extraction line(4) for gas generated from volatile components is connected to upper regions(11,12) of the container. At least one phase separation chamber(2) is disposed at the upper region and composed of an inlet(20) for the liquid to be treated; a lower opening(210) formed at a polymer discharge region; and one or plural upper openings(220) formed at a gas exhaust region.
