Process and apparatus for the continuous production of vinyl chloride polymers in aqueous emulsion

摘要

A continuous process and an apparatus for the polymerization of vinyl chloride in aqueous emulsion wherein the liquid reaction mixture is fed into the lower part of a vertical, cylindrical vessel, the liquid level in the vessel is adjusted to at most 97% of the total interior height of the vessel, the reaction mixture is stirred with a stirrer which is totally immersed in the liquid and extends over 15 to 60% of the total interior height of the vessel and the produced polymer emulsion is laterally discharged from the upper part of the vessel.
