Abstract
A novel process for the preparation of methyl glucoside-amine-based polyols which involves reacting starch with methanol in the presence of an acid catalyst to form a crude methyl glucoside reaction product. An amine compound is admixed with the reaction product, and the mixture is then oxyalkylated with a lower alkylene oxide. Polyurethane foams may be prepared by reacting the resulting polyether polyols with an organic polyisocyanate in the presence of a foaming agent and a reaction catalyst. The physical properties of the resulting foams are excellent.
