Abstract
Provided is an aqueous composition having pH of 8 or higher and comprising (a) a solid phase comprising dispersed particles that comprise an amount of ethylcellulose polymer, (b) an amount of one or more polymeric dispersants, wherein said polymeric dispersant has a weight-average molecular weight of 5,000 daltons or higher, and wherein said polymeric dispersant has an acid value of 60 to 190 mg KOH/g of polymer. Also provided is a method of making such a composition using an extruder. Also provided is a film made by removing water from such a composition.
