A novel method for preparing anionic, cationic or non-ionic polymeric microemulsions comprising a multi-step process to achieve high solids and low emulsifier and oil content. The polymeric microemulsions are useful in papermaking as retention aids, in solid-liquid separation as flocculants and in enhanced oil recovery as a drive fluid.
