ABSTRACT:
This invention is a process for comminuting a cellulose ether which comprises extruding a hydrated cellulose ether through a plurality of orifices, each orifice having a cross-sectional area of from about 7.5.times.10.sup.-9 m.sup.2 to about 1.times.10.sup.-6 m.sup.2, to form an elongated extrudate, and then cutting the elongated extrudate to desired length. The high density cellulose ether product is typically cold water dispersible, non-dusty, and free flowing.
