    摘要: A method for the production of micropowders from cellulose ethers or cellulose comprising(a) subjecting a cellulose ether or a cellulose having a fine-fiber, cottony or woolly structure to a consolidation or embrittlement sufficient whereby in one mill pass through a jet mill under standard conditions 98% by weight of the consolidated or embrittled material charged is recovered as a powder of less than 100.mu., and(b) subjecting the consolidated or embrittled material to a grinding step producing a size reduction sufficient that a grain size distribution with at least 90% by weight of less than 125.mu. is attained.
