Described are anionic surfactants which are made by (1) reacting maleic acid, fumaric acid, or mixtures thereof with at least one selected poly(oxyalkylated) alcohol in the presence of a peroxy-type free radical initiator to form a carboxylic acid group-containing addition product and (2) sulfating said addition product with a sufficient amount of a sulfating agent (i.e. sulfamic acid) to convert at least a major proportion of the terminal hydroxyl groups to sulfate groups. These surfactants exhibit excellent surface activity as well as being highly soluble in caustic solutions.

Sulfated addition products of selected unsaturated dicarboxylic acids

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.

Methyl glucoside-amine-based polyether polyols and polyurethane foams

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.
