摘要：A fine cellulose powder consists of rounded particles, has a viscosity averagepolymerization degree of 20 - 150, and exhibits a water absorption coefficient of 100 %or more relative to its own weight. A method of producing the fine cellulose powdercomprises the steps of aging alkali cellulose to reduce its average polymerization degreeand increase its friability, neutralizing the aged alkali cellulose, and pulverizing the result,preferably in a jet mill.
