Cellulose Ester Polymer Product With Increased Melt Flow Properties and Reflectance

A polymer composition comprising:

• a cellulose ester polymer, the cellulose ester polymer being present in the polymer composition in an amount greater than about 40% by weight;
• a plasticizer;
• and
• a property enhancing agent, the property enhancing agent comprising an acidic species having a Pka value of from about 2 to about 6, the property enhancing agent being present in an amount sufficient to increase a melt flow rate of the composition and/or to increase a reflectance of an article formed from the composition in comparison to the same composition without the property enhancing agent and with the cellulose ester polymer in the same amount.
