摘要：

The migration of the surfactant sodium dodecyl sulfate (SDS) to the film-air (F-A) and film-substrate (F-S) interfaces during coalescence of a latex of methyl methacrylate and ethyl acrylate functionalized with methacrylic acid was monitored by IR and ATR-FTIR spectroscopic techniques. Both F-A and F-S interfaces showed surfactant enrichment, revealing a nearly parabolic distribution of surfactant throughout the film.
