ABSTRACT:
A novel process for the preparation of starch-amine-based polyols which involves reacting starch with a polyhydric alcohol in the presence of an acid catalyst to form a crude polyglucoside reaction product, the proportion of alcohol to starch being at least 0.3 mole of alcohol per glucose unit weight of starch. 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.
