Abstract

PURPOSE: To obtain the titled substance, useful as a viscosity increasing agent, etc. at a high reaction efficiency in a good working envionment, by adding small amounts of an organic solvent, water and a caustic alkali to a nongranular polysaccharide, and reacting the resultant mixture with an alkylene oxide in a state of slightly wet polysaccharide.
CONSTITUTION: A mixed solution of 2W30pts.wt. organic solvent, e.g. methanol, with 0W20pts.wt. water and 2W20pts.wt. caustic alkali, e.g. caustic soda, is added to 100pts.wt. nongranular polysaccharide, e.g. cellulose, and the resultant mixture is stirred well. An alkylene oxide, e.g. propylene oxide, is then added to the resultant mixture and reacted at 40W120°C in such a state that the polysaccharide is slightly wet. After cooling, the reaction mixture is neutralized with acetic acid, etc. to give the aimed polymer.
