A suspension-enhancing adhesive additive is described for an aqueous, starch-containing, liquid adhesive to be used in manufacturing corrugated paperboard. The additive includes a suspension-enhancing agent with a synthetic liquid polymer component. The polymer component is emulsifiable in the adhesive, and is capable of enhancing suspension of such starch. The polymer component may be based on at least one acrylic-acid monomer, and may be a copolymer based on an acrylic-acid monomer and an aromatic monomer substituted with an acrylate compound. The agent may also include an effective amount of an alcohol-ester coalescing agent. Also described is a liquid adhesive composition for manufacturing corrugated paperboard, which composition incorporates the additive. Also described is a method of preparing a starch-based, liquid adhesive composition for manufacturing corrugated paperboard.
