aDetermination of color and haze made on CAB solution using Pt-Co standard (color) and a monodisperse latex suspension (haze). Analysis is performed with a Gardner Model XL-835 Colorimeter.
bViscosity determined by ASTM Method D 1343. Results converted to poises (ASTM Method D 1343) using the solution density for Formula A as stated in ASTM Method D 817 (20% Cellulose ester, 72% acetone, 8% ethyl alcohol).
