Abstract
A polymer composition containing cellulose acetate in combination with one or more plasticizers and one or more biodegradable fillers. The biodegradable fillers can include monosaccharides, polysaccharides, esters thereof, and mixtures thereof. The polymer composition is formulated so as to have properties similar to petroleum-based polymers for producing, for example, single-use biodegradable articles.
