ABSTRACT:
A water-soluble polymer of monoallylamine is used as a demulsifying agent for breaking oil-in-water emulsions. This enables rapid and efficient separation between the aqueous phase and the liquid organic phase by a variety of conventional physical techniques such as settling and decantation, centrifugation, and the like.
