a - Viscosity 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).
b - Number-average molecular weight values, MW_n, are polystyrene-equivalent molecular weights determined using size exclusion chromatography.
