Surfactant behavior and its influence on the viscosity of associative thickeners solutions, thickened latex dispersions, and waterborne latex coatings

摘要

The scenario of incremental increases in surfactant concentration was repeated with the nonionic surfactant, NP(EO)^sub 12^, which has a limiting surface area of 1.55 nm^sup 2^/mol. The adsorption data for the NP(EO)^sub 12^/ telechelic HEUR were obtained from our studies in Figure 6. In these studies, the amounts of NP(EO)^sub 12^ desorbed from a surfactant saturated surface, due to HEUR adsorption, is measured by UV analysis.
