Abstract

Understanding the microscopic mechanisms of film formation in polymer dispersions is a complex analytical and physical challenge. In this contribution, we present results from parallel gravimetric and NMR profiling experiments along with a semiempiric model approach to establish a systematic relation between both data sets. As a result of the semiempiric model, a critical water content at which rotation dynamics of the polymer particles changes can be determined. Furthermore, it is shown that the addition of film-forming agents to the dispersion shifts the critical water content to higher values.
