Abstract
A polymer composition containing cellulose acetate in combination with one or more impact modifiers is described. The polymer composition can also contain a plasticizer and a bio-based polymer in addition to the cellulose acetate. The polymer composition is formulated so as to have properties similar to petroleum-based polymers for producing, for example, single-use biodegradable articles.
