    摘要: A crosslinking additive for imparting water resistance to starch-based alkaline corrugating adhesive compositions is prepared by reacting acetone and formaldehyde under aqueous alkaline conditions at 20.degree.-80.degree. C. in a molar ratio of from 2 to 5 moles of formaldehyde per mole of acetone. The condensate is thereafter treated with from 1.0 to 2.0 moles of hydrogen peroxide per mole of unreacted formaldehyde which oxidizes the residual formaldehyde to formic acid. The treated crosslinking additive will contain less than 0.4% unreacted formaldehyde and may be added directly to a starch-based corrugating adhesive.
