ABSTRACT:
This application discloses polyether products of starch with several different etherifying agents, preferably the alkylene oxides, where the moles of etherifying agent per anhydroglucose unit are in the range from about 3.5 to about 50. Also disclosed are the hydrolyzates of the starch polyethers. Methods of producing the starch polyethers by base-catalyzed reactions are also described. Several applications for the polyether products are described, including rigid and flexible polyurethane foams, film-forming compositions, and foundry resin binders.
