    摘要: The invention is a process for removing excess surfactant from a resin dispersion. The excess surfactant is initially required to form the dispersion, but it is not needed to maintain the stability of the dispersion. The process involves the addition of an acid to a dispersion. The acid reacts with one of the surfactants, and the acidified surfactant returns to its original non-neutralized form or its original hydrophobic form and no longer has the structural capacity to serve as a surfactant. The reduction of the surfactant concentration in the dispersions improves the cohesive strength of adhesives made with the dispersions.

    摘要: Anionic emulsifiers based on rosin acid or derivatives thereof, and to methods of preparing said emulsifiers. The emulsifiers are useful for preparing tackifier dispersions having improved properties with respect to foam stability. As such, said tackifier dispersions are advantageously used in water-based adhesives providing improved adhesive and cohesive properties. The adhesives may be used for labels on any kind of surface, packaging applications, flooring adhesives, road markings or for any type of water-based tapes, barrier coatings or sealants.
