Method of preparing water-in-oil polymer microemulsions and use of the polymers |
摘要 |
<p>Described is a 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 and/or small aqueous phase droplets. 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.</p> |
