Abstract
Water soluble cellulose acetate composition having improved processability and tensile properties suitable for application as films, coatings and fibers and comprising one or more lower molecular weight water soluble cellulose acetate components and one or more higher molecular weight water soluble cellulose acetate components, and wherein the lower molecular weight water soluble cellulose acetate components have solution viscosities at least 20 percent of that of the higher molecular weight water soluble cellulose acetate components. An exemplary composition comprises from about 85 to 98 percent by weight of a lower molecular weight water soluble cellulose acetate component having a solution viscosity of form about 5 to 50 cps and from about 15 to 2 percent by weight of a higher molecular weight water soluble cellulose acetate component having a solution viscosity of greater than 100 cps.
