摘要: Relaxation behaviors of isotactic, atactic, and syndiotactic poly(methyl methacrylate) (PMMA) monolayers at the air/water interface were investigated three different temperatures. The monolayer characteristics stereoisomers studied in terms surface pressure–area per molecule (π-A) isotherm, area relaxation, pressure relaxation. results show that pressures inflection points π-A isotherms PMMA decrease with an increase temperature. collapse also decreases as temperature is elevated. It was shown likely for first time relaxation process could be described by a model considering nucleation growth mechanisms. simulation parameters 30 mN/m are very similar, indicating similar © 2007 Wiley Periodicals, Inc.
