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.
A 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 said lower molecular weight water soluble cellulose acetate components have solution viscosities at least 20 percent lower than that of said higher molecular weight water soluble cellulose acetate components.
A water soluble cellulose acetate composition having improved processability and tensile properties suitable for applications as films, coatings and fibers and comprising a low molecular weight water soluble cellulose acetate component having a solution viscosity of from about 5 to 50 cps and a higher molecular weight water soluble cellulose acetate component having a solution viscosity of greater than about 100 cps.
A water soluble cellulose acetate powdered blend having improved processability and tensile properties comprising from about 85 to 98 percent by weight of a low molecular weight water soluble cellulose acetate component having a solution viscosity of from 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.
