摘要： A particulate cellulose derivative is obtained in a process of grinding and drying a moist cellulose derivative which comprises the steps of A) providing a cellulose derivative having a moisture content of from 60 to 95 percent, based on the total weight of the moist cellulose derivative, B) grinding and partially drying the moist cellulose derivative in a gas-swept impact mill; and C) contacting the ground and partially dried cellulose derivative with an additional amount of a drying gas outside the gas-swept impact mill. The obtained particulate cellulose derivative has a high untapped bulk density and a good flowability.

摘要： In a process for producing a particulate polysaccharide derivative by dry-grinding a moist polysaccharide derivative, one or more of the properties selected from median diameter, median length, bulk density and dissolution rate is controlled by controlling the temperature of the polysaccharide derivative prior to thy-grinding. Advantageously one or more of the properties selected from median diameter, median length, bulk density and dissolution rate of the particles after thy-grinding is adjusted to a first value by a first temperature of the polysaccharide derivative prior to thy-grinding and is adjusted to a second value by a second temperature.

摘要： A simplified and more efficient process is described for drying (and heat-treating) a lyotropic polybenzazole film in which the film is constrained in only the machine direction during drying (and heat-treating). The amount of stretching in the transverse direction the film undergoes prior to it being coagulated can be increased to compensate for the relaxation of the film during the drying process and the lack of stretching during the heat-treating process. Films made in this manner have acceptable finished properties.
