Sulphonamide resins.

The sulphonamide resins were developed from para toluenesulphonamide, a byproduct obtained in the manufacture of saccharin (synthetic sweetening agent).

Para toluenesulphonamide, condensed with formaldehyde or other aldehyde, forms a viscous mass which, on heating, is converted to a hard colorless resin. Such resins are compatible with cellulose acetate or nitrocellulose in lacquers, the combination yielding clear, colorless lacquers of good gloss and adhesion. Other possible uses are as an adhesive in safety glass, in certain molding compositions, in insulating materials, and to deluster artificial silk.

Domestic production of sulphonamide resin is entirely by the Monsanto Chemical Co., St. Louis, Mo. It is marketed under the trade name Santolite.
