    摘要： The invention relates to a composition in the form of a solid and suitable as a dispersant for inorganic solids suspensions, comprising A) at least one water-soluble polymer comprising polyether groups, and B) at least one water-soluble condensation product comprising acid groups and/or salts thereof and based on monomers, the monomers comprising at least α) a monomer having a ketone radical and β) formaldehyde. Further disclosed are a method for producing the composition of the invention, and the use thereof in an inorganic binder composition.

    摘要： Hydrophilic, hydrolytically-stable synthetic resins obtainable by reacting a hydroxyl-functional synthetic resin such as a ketone, ketone/aldehyde and/or urea/aldehyde and/or a hydrogenated product of the hydroxyl-functional synthetic resin thereof with a polycarboxylic acid, polycarboxylic anhydride, polycarboxylic ester and/or polycarbonyl halide, where 70-100 mol % of the polycarboxylic acid and/or derivatives is linked chemically via an ester linkage to the hydroxyl-functional synthetic resin by way of only one single function and 0-30 mol % of the acid and/or acid derivative is so linked by way of more than one function.

    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.
