  • Process for shaping cellulose ethers
    Publication number: 20060205935
    Abstract: The present invention relates to a process for the manufacture of cellulose ethers. The process involves: (a) providing a perforated disk having a plurality of perforations; and (b) forcing feed cellulose ether through at least some of the perforations of the perforated disk, thereby forming compressed cellulose ether. The compressed cellulose ether formed in accordance with the method of the present invention has a higher bulk density and a more uniform particle size distribution than known cellulose ethers prepared by other processes.
