Anotations

Scope note:

A class of water-soluble polymers with a cellulose backbone and ether-containing substituents. Cellulose ethers are white bulky solids that form clear, hygroscopic films. They are made by treating cellulose with concentrated sodium hydroxide followed by etherification with one or more reagents such as methyl chloride, ethyl chloride, ethylene oxide or propylene oxide. They are used as adhesives, poultices, consolidants, and coatings.
