Cellulose triacetate and process for producing the same |
| abstract |
Cellulose triacetate having satisfactory filterability, i.e., having a clogging constant (K) as determined by the following method of 70 or lower. (Measurement method) Cellulose triacetate is dissolved in a methylene chloride/methanol [9/1 (by weight)] mixed solvent to obtain a solution having a concentration of 16 wt.% (on a solid basis). This solution is filtered through a metal gauze filter medium at a constant filtration pressure of 3 kg/cm2 and at 25 °C to measure at intervals the amount of the solution which has been filtered. From the found values, the slope of a straight line represented by t/V ∩t (wherein t represents the filtration time (sec) and V represents the filtered amount (ml) is calculated. The clogging constant (K) is determined using the equation K=(slope)x2x104. |
