摘要：
This invention relates to a process for reducing the viscosity of cellulose ethers by reacting a water-soluble cellulose ether with ozone in the presence of water, wherein said cellulose ether which is moist with water and has a dry content of from 20 to 95% by weight is reacted with an ozone/oxygen mixture or with an ozone/air mixture at a temperature of about 0.degree. to 60.degree. C.
