Preparation of discrete microdroplets of an oil in water

摘要

What is provided herein is a method for preparing discrete microdroplets of an oil in water stabilized by in situ polymerization of a water-soluble vinyl monomer. The method comprises dispersing the oil in water, adding the water-soluble vinyl monomer, preferably vinylpyrrolidone, optionally with a comonomer, and polymerizing the monomer or comonomers in situ such that the oil is stabilized in the resulting polymer solution as discrete microdroplets.
