Abstract
A process for reducing the average molecular weight of a cellulose ether comprises the step of contacting a cellulose ether with an acid to partially depolymerize it to a lower molecular weight in a diluent comprising at least 50 weight percent of an organic hydroxylic compound having at least one hydroxy group and at least two carbon atoms.
