ABSTRACT:
A polyurethane foam which is a reaction product of a polyol reactant, an organic polyisocyanate reactant, a reaction catalyst and a foaming agent, said polyol reactant is made by (1) reacting starch with methanol in the presence of an acid catalyst to form a crude methyl glucoside reaction product; (2) then admixing this reaction product with an amine in the presence of a basic catalyst followed by (3) oxyalkylating this mixture with a lower alkylene oxide.
