The fact that the viscosity of acetone solutions of cellulose diacetate CDA DATs can be reduced by the addition of small quantities of water has been known for a long time. It is given practical application in the production of acetone fiber. An analogous viscosity reduction effect is achieved when water or butanol about 3 by volume is added to acetone solutions of partially saponified polyvinlyl acetate. The literature contains recommendations on the introduction of CDA together with aqueous semicolloidal surfactants PAV of the alkylbenzol sulfonate type into acetone solutions. In our study, using Na salts of perfluoroenanthic perfluorogentylol acid we showed that is was possible to reduce the effect of viscosity in CDA solutions in acetone by introducing small quantities of highly surface-active fluorocarbon substances fluorothenzides in the presence of water.
