Abstract: Cellulose ester plastics may be formulated to have a depressed melt processing temperatures, improved heat resistance, increased mechanical stability, or some combination thereof. For example, in some instances, a cellulose ester plastic comprising: a cellulose ester at about 20% to about 90% by weight of the cellulose ester plastic; and a plasticizer that comprises a carbonate ester, a polyol benzoate, or both, wherein the plasticizer is at about 2% to about 40% by weight of the cellulose ester plastic, wherein the cellulose ester plastic is melt processable.
