Abstract
Cellulose ether derivatives comprising a hydrophobic substituent having an unsaturated alkyl portion are disclosed. The unsaturation in the alkyl portion of the hydrophobic substituent can promote crosslinking of the cellulose ether derivative. The cellulose ether derivatives are useful as ingredients in latex compositions. The cellulose ether derivatives can provide associative thickening and rheological properties to latex composition during storage and application. In addition, after the latex composition is applied to the surface to be coated, the cellulose ethers of the present invention can promote crosslinking of the latex film to provide a hard and durable coating. Latex paint compositions comprising the cellulose ether derivatives of the present invention are also disclosed.
